How do you think we could print a sentence that uses a variable along with other text (ie: “My name is Joe” where ‘Joe’ is a var
Sphinxa [80]

This is for Python

name = 'Joe'

print(f'My name is {name}')

This is called string formatting. Using f before the text. This is another way

name = 'Joe'

print('My name is', Joe)

But I found that string formatting is cleaner and much more useful
