I don't know how to get input depending on user choice. I.e. 'How many numbers you want to enter?' if answers 5, then my array has 5 spaces for 5 integers in one line separated by space.

num = []
x = int(input())
for i in range(1, x+1):
    num.append(input())

Upper code works, however inputs are split by enter (next line). I.e.:

2
145
1278

I want to get:

2
145 1278

I would be grateful for some help.

EDIT:

x = int(input())
while True:
    attempt = input()
    try:
        num = [int(val) for val in attempt.split(" ")]
        if len(num)== x:
            break
        else:
            print('Error')
    except:
        print('Error')

This seems to work. But why I'm getting "Memory limit exceeded" error?

EDIT: Whichever method I use, I get the same problem.

x = int(input())
y = input()
numbers_list = y.split(" ")[:x]
array = list(map(int, numbers_list))
print(max(array)-min(array)-x+1)

or

x = int(input())
while True:
    attempt = input()
    try:
        num = [int(val) for val in attempt.split(" ")]
        if len(num)== x:
            break
        else:
            print('Error')
    except:
        print('Error')

array = list(map(int, num))
print(max(array)-min(array)-x+1)

or

z = int(input())
array = list(map(int, input().split()))
print(max(array)-min(array)-z+1)

The easiest way to do this would be something like this:

input_list = []

x = int(input("How many numbers do you want to store? "))

for inputs in range(x):
    input_number = inputs + 1
    input_list.append(int(input(f"Please enter number {input_number}: ")))

print(f"Your numbers are {input_list}")

Is there a reason you want the input to be on one line only? Because you can only limit how many numbers you store (or print) that way, not how many the user inputs. The user can just keep typing.

for loop one line in python, Solution. If you strictly want a one-liner, then this is the solution: get_cubes = lambda x: [pow(i, 3) for i in range(0, x+1, 3)]. But since clarity and� One-Line While Loops. Mastering While Loops Katy Gibson 02:17 3 Comments. Mark as Completed. Intro to While Loops in Python 01:11. Basic While Loop Structure 03:07.

Assuming you want to input the numbers in one line, here is a possible solution. The user has to split the numbers just like you did in your example. If the input format is wrong (e.g. "21 asd 1234") or the number does not match the given length, the user has to enter the values again, until a valid input is made.

x = int(input("How many numbers you want to enter?"))
while True:
    attempt = input("Input the numbers seperated with one space")
    try:
        num = [int(val) for val in attempt.split(" ")]
        if len(num)==x:
            print(num)
            break
        else:
            print("You have to enter exactly %s numbers! Try again"%x)
    except:
        print("The given input does not match the format! Try again")

Python One Line For Loop [A Simple Tutorial], How to Write a For Loop in a Single Line of Python Code? Method 1: If the loop body consists of one statement, simply write this statement into the same line: for i in range(10): print(i) . Method 2: If the purpose of the loop is to create a list, use list comprehension instead: squares = [i**2 for i in range(10)] . Python’s easy readability makes it one of the best programming languages to learn for beginners. A good example of this can be seen in the for loop.While similar loops exist in virtually all programming languages, the Python for loop is easier to come to grips with since it reads almost like English.

You can use this without needing x:

num = [int(x) for x in input().split()]

Taking multiple inputs from user in Python, Developer often wants a user to enter multiple values or inputs in one line. In C ++/C user can take multiple inputs in one line using scanf but in� In Python, to provide multiple values from user, we can use − input () method: where the user can enter multiple values in one line, like − >>> x, y, z = input(), input(), input() 40 30 10 >>> x '40' >>> y '30' >>> z '10' From above output, you can see, we are able to give values to three variables in one line.

If you want the numbers to be entered on one line, with just spaces, you can do the following:

x = int(input("How many numbers do you want to store? "))
y = input(f"Please enter numbers seperated by a space: ")
numbers_list = y.split(" ")[:x]
print(f"We have a list of {len(numbers_list)} numbers: {numbers_list}")

Even if someone enters more than the amount of promised numbers, it returns the promised amount.

Output:

How many numbers do you want to store? 4
Please enter numbers seperated by a space: 1 4 6 7
We have a list of 4 numbers: ['1', '4', '6', '7']

How to input multiple values from user in one line in Python , Recommended Posts: How to write an empty function in Python - pass statement ? Operator Functions in Python | Set 2 � Time Functions in Python | Set� The break, continue and pass statements in Python will allow one to use for and while loops more efficiently. Python also supports to have an else statement associated with loop statements. In the above-mentioned examples, for loop is used.

Try this.

x = int(input())
num = [] # List declared here
while True:
    try:
        # attempt moved inside while
        # in case input is in next line, the next line
        # will be read in next iteration of loop.
        attempt = input() 

        # get values in current line
        temp = [int(val) for val in attempt.split(" ")]

        num = num + temp
        if len(num) == x:
            break
    except:
        print('Error2')

Maybe the bot was passing integers with newline instead of spaces, in which case the while loop will never terminate (assuming your bot continuously sends data) because every time, it will just re-write num.

Note - this code will work for both space as well as newline separated inputs

How to take more than one input in one line in Python 3.0, x,y,z would be string , so type casting must be done as per requirement .

For and Read-While Loops in Bash, Only until we reach done , and hit Enter, does the for-loop do its work. I wrote four lines of code to do what it takes a single line to do, echo 'Hi' . for working with them is far more direct and straightforward in Bash than in Ruby or Python. Taking multiple inputs from user in Python Developer often wants a user to enter multiple values or inputs in one line. In C++/C user can take multiple inputs in one line using scanf but in Python user can take multiple values or inputs in one line by two methods. Using split () method

Comments
  • You can not prevent user to enter 5 number split by space. because after pressing enter the values receives in input() in your python code. you can only choose the first 5. is it ok ?
  • You cant limit the user entering more than the specified number, you might want to rethink on how you want to structure your input.
  • Ok, so explain to me how you escape out of the while loop. Is there ANY condition where it ends en continues to the end of the script?
  • I could not tell you why, as you did not provide the line of my code where this error occurs nor the input string you used. I can't see a reason why this code should exceed your memory limit, if the string you put in is small. If this happens with all code provided, the error is maybe in another part of your code.
  • It's all code provided. This exercise is going to be corrected by the bot. It is programmed to enter number of inputs in the first line, and in the next line it enters x integers separated by space. For array = list(map(int, input().split())) or num = [int(x) for x in input().split()] I'm getting "memory limit exceeded".
  • There is a specific reason. This exercise is going to be corrected by the bot. It is programmed to enter number of inputs in the first line, and in the next line it enters x integers separated by space. For array = list(map(int, input().split())) or num = [int(x) for x in input().split()] I'm getting "memory limit exceeded".
  • This solution quite works. Please check my edited post.
  • I like your solution, but I get error described in the edited post. =(
  • Then there's probably a problem on the bot you're entering it into. This should in no way use too much memory.
