I'm generating a list of random digits, but I'm struggling to figure out how to output the digits in a single row without the square brackets?

import random 
def generateAnswer(answerList):

    listofDigits = []
    while len(listofDigits) < 5:
        digit = random.randint(1, 9)
        if digit not in listofDigits:
            listofDigits.append(digit)
    return listofDigits

def main():
    listofDigits = []
    print(generateAnswer(listofDigits))

main()

You can unpack a list and use the sep argument:

print(*generateAnswer(listofDigits), sep=' ')

How to print a list without brackets in Python, How do I print a list of values without brackets in Python? Python | Remove square brackets from list Sometimes, while working with displaying the contents of list, the square brackets, both opening and closing are undesired. For this when we need to print whole list without accessing the elements for loops, we require a method to perform this.


print(", ".join([str(i) for i in generateAnswer(listofDigits)]))

Try this:

listofDigits = []
print(str(generateAnswer(listofDigits))[1:-1])

Also, if generateAnswer initialize and return the list, then you don't need to pass in an empty list. Another thing is that if you want to generate a non-repeating random list, you can use random.sample and range.

I think this is better:

import random 
def generateAnswer():
    return random.sample(range(1, 10), 5)

def main():
    print(str(generateAnswer())[1:-1])

main()

Hope it helps!

Print list without brackets in a single row, How do you remove brackets from a list in Python? @FredrickGauss if you add from __future__ import print_function it'll work in python 2 a list of numbers to a a list without square brackets in python-1.


The reason you’re getting the brackets is because the list class, by default, prints the brackets. To remove the brackets, either use a loop or string.join:

>>> print(' '.join(map(str, listofDigits)))
9 2 1 8 6
>>> for i in listofDigits:
    print(i, end=' ')


9 2 1 8 6 

Note that the last method adds a space at the end.

Note that in the first method, the arguments need to be cast to strings because you can only join strings, not ints.

Python, comprehensions evaluate in the same manner that they unwrap (i.e. add newline and tab for each new loop. complex numbers - extension of the familiar number system which all numbers are expressed as real and imaginary. decorator - A function that modifies another function.
