How to manipulate strings in lists?

I am have been trying to learn how to manipulate lists. Example I have successfully done a simple program that asks the user for a numerical input and returns the corresponding month. Below is an example of what my solution is:

months = ['January', 'February',
          'March', 'April', 'May',
          'June', 'July', 'August',
          'September', 'October', 'November', 'December']

n = int(input("Enter a value between 1 and 12: "))

# Process & Output:
if 1 <= n <= 12:
    print ("The month is", months[n-1])
else:
    print ("Value is out of the range")

My current question is, how would I go about asking the user to pick from the list but by inputting a string rather than an int value?

Example:

subjects= ['Maths','English','Science','History','Business']
n = (input("What is your favourite subject this semester? "))

I would not be able to use the above method because it requires an int value.

You have already asked the user for the subject. Now you have to find that in subjects list. To do it just use this

if n in subjects: 
    print ("valid subject")
else:
    print("invalid subject")

If you'd like to check a string input against the list, you can do it simply using in:

subjects = ['Maths','English','Science','History','Business']

subj_in = input("What is your favourite subject this semester? ")

if subj_in in subjects:

    print('Your favorite subject is ', subj_in)

else:

    print('Oh, they offer a course for that?')

Here you go:

subjects= ['Maths','English','Science','History','Business']

n = (input("What is your favourite subject this semester? "))

if n in subjects:
    print('great')
else:
    print('even better')
