how to use variable in input function python

Question

I'm new to python and trying to create a program to calculate grade. I've been stuck on below for over an hour now so any help appreciate.

assessment=[] 
weight=[] 
assign_number = int(input('How many assessment : ')) 
for i in range(assign_number): 
 asses_name =input('Enter name of assessment: ') 
 assessment.append(asses_name) 
 asses_value = int(input(print('How many marks is the',assessment[i],'worth : '))) 
 weight.append(asses_value)

the problem is the asses_value keep returning none?example is below

How many assessment : 3
Enter name of assessment: test
How many marks is the test worth :
None

Any hint is appreciated, thanks everyone

Answer 1

The print() function in Python always returns None. So you need to remove it from this line:

asses_value = int(input(print('How many marks is the',assessment[i],'worth : ')))

Simply passing a string to the input function does what you need:

asses_value = int(input('How many marks is the ' + assessment[i] + ' worth : '))

Note that you can only pass a single string to input() though, which is why I have used the string concatenation operator + rather than passing three comma-separated strings.

As pointed out in the comments, an improvement to the above would be to use string formatting:

asses_value = int(input('How many marks is the {} worth : '.format(assessment[i])))

Hope! This code will help you out

assessment=[] 
weight=[] 
assign_number = int(input('How many assessment : ')) 
for i in range(assign_number): 
 asses_name =input('Enter name of assessment: ') 
 assessment.append(asses_name) 
 asses_value = int(input('How many marks is the ' +assessment[i]+' worth : '))
 weight.append(asses_value)

Update: You tried to print the the value while taking the input that's why all the error occur
