Python: Immutability

Imagine we have this call:

name = 'Tirion'
print(name.upper())  # => TIRION
# What will this call print on the screen?
print(name)  # => ?

Calling the .upper() method returns a new value with all letters converted to upper case, but it does not change the original string. So inside the variable will be the old value: 'Tyrion'. This logic holds true for methods of all primitive types.

Instead of changing the value, you can replace it. This requires variables:

name = 'Tirion'
name = name.upper()
print(name)  # => TIRION

Instructions

User input data often contains extra spaces at the end or beginning of a string. They're usually cut out using a method .strip(), for example, it was hello\n' and now it's hello'.

Update the first_name variable by writing the same value to it, but this time processed by the .strip() method. Print the result.
