I need to create a subroutine in python which identifies the highest number in a list, but I don't know how to move to the next item in the list using a loop

I've tried to add 1 to the counter, but I am not entirely sure of the of the syntax

number = []
for i in range(0, 5): # set up loop to run 5 times
    numbers = int(input('Please enter a number: '))
    number.append(numbers) # append to our_list
tempmax = number[0]
maximum = 0
for i in number:
    if tempmax > maximum:
        maximum = tempmax
        tempmax = number[+1]
    else:
        tempmax = number[+1]

print(maximum)

This is what I've tried, but I don't really know how to fix it. Any tips would be appreciated.

A for loop will give you each item in the sequence you are iterating over.

You named the input number numbers and your list of numbers number. Swap those names around to be clearer.

You are iterating over a list of numbers so each item is a number. You named it i which probably made you think it was an index, but it's not, it's the actual number. Give it a good name:

for number in numbers:

Then you want to test whether the number is the maximum:

    if number > maximum:
        maximum = number

Loops and lists, Every element in a list is associated with an index, which reflects the position of the Two examples are C.append(v) , which appends a new element v to the end of the After having printed the list element with value 100 , we move on to the  Range("A2").Select ' Establish "For" loop to loop "numrows" number of times. For x = 1 To NumRows ' Insert your code here. ' Selects cell down 1 row from active cell. ActiveCell.Offset(1, 0).Select Next End Sub To Search a Dynamic List or a List with an Unknown Number of Rows. This code moves down column A to the end of the list.

Is this want you to want to do?

number = []
for i in range(0, 5): # set up loop to run 5 times
    numbers = int(input('Please enter a number: '))
    number.append(numbers) # append to our_list
tempmax = number[0]
maximum = 0
for i in range(len(number)-1):
    if tempmax > maximum:
        maximum = tempmax
        tempmax = number[i+1]
    else:
        tempmax = number[i+1]

print(maximum)

If you want to determine maximum value in a list, you can also do something much easier like this (without having to recreate the wheel).

max_val = max(number)
print(max_val)

ProjPython – Lists and for-loops, So far, we've needed a new variable name for each new piece of information we You can find out how many items are in a list using the Python built-in function len . Create a new, reversed copy of the list, leaving the original list intact. When you complete the task on the first item, you take the next item and perform the same action on the item. Then you continue the same process until you have processed through all the items in the collection. The syntax of a PowerShell ForEach construct is shown below: Syntax: ForEach (Item In Collection) { ScriptBlock or sequence of commands }

As the for loop seeks the next item automatically and loads it in the variable you asked it to... for YOUR_VAR in YOUR_ITERABLE, you either need to work on the items you want, or on the indexes.

So, if your items were arr = [10, 20, 30, 40, 50], you could access them both ways.

for item in arr:
     print(item) # Will print successively 10, then 20, then 30, then 40, then 50.

array_indices = len(arr)
for index in array_indices:
    print(index) # will print successively 0, 1, 2, 3, 4
    print(arr[index]) # will print successively 10, then 20... 30, 40, 50

Sams Teach Yourself Python in 24 Hours, Perhaps you want to move to the next item in the list before finishing the block of code beneath the for loop. Maybe you encountered some bad data, or maybe  For Next Loop. The ‘For Next’ loop allows you to go through a block of code for the specified number of times. For example, if I ask you to add the integers from 1 to 10 manually, you would add the first two numbers, then add the third number to the result, then add the fourth number to the result, as so on..

Possibly you are looking for max(numbers). It will return the biggest number in the list.

If you want to get index of the number after maximum, try numbers.index(max(numbers)) + 1

a = [1, 2, 3, 4, 1, 2, 3]
>>> max(a)
4
>>> a.index(max(a))
3
>>> a[a.index(max(a)) + 1]
1

Note: list.index() return index of the first maximum.

Python in 24 Hours, Sams Teach Yourself, Perhaps you want to move to the next item in the list before finishing the block of code beneath the for loop. Maybe you encountered some bad data, or maybe  Instead, we can use the continue statement to skip a single iteration (“loop”) of a for loop and move to the next. When Python sees continue while executing a for loop on a list, for example, it will stop at that point and move on to the next item on the list. Any code that comes below the continue will not be executed.

Beginning ASP.NET 1.1 with VB.NET 2003, The ForNext loop runs for a pre-specified number of times and no more, while the code between Do While and loop you move to the next item on the list. Return Value from next() The next() function returns the next item from the iterator.; If the iterator is exhausted, it returns the default value passed as an argument.; If the default parameter is omitted and the iterator is exhausted, it raises StopIteration exception.

Comments
  • use i=0 tempmax=number[i] i+=1, use a additional varible i and then increment it
  • Aren't you simply looking for max(numbers)?
  • You need to read the documentation for for.
