quick question on printing results in python

Question

I am currently trying to print the results of list using a for loop in python, but I want the last number to print a space, then a newline. for ex.

hourly_temperature = [90, 92, 94, 95]

for num in hourly_temperature:
    print(num, '-> ', end= '')

I'm getting 90 -> 92 -> 94 -> 95 -> but i want 90 -> 92 -> 94 -> 95

I've tried using len and range with if else statemets, but i didt really work.

Answer 1

If you want to use a for loop you can loop over every element except for the last one, and then print the last one manually, like this:

for num in hourly_temperature[:-1]:
    print(num, '->', end='')
print(num[-1])

It might be simpeler to use join though, for example:

strs = [str(x) for x in hourly_temperature] #convert values to str
print('->'.join(strs))

This converts your list to string with a '->' between every two elements.

Answer 2

Try this:

' -> '.join(str(element) for element in hourly_temperature)
