for i in range(1, 11):

python f strings
'''
In python, rather than adding pieces of string together, you can use
f-strings to insert variables into strings. This makes your code much
more easier to read.

# OLD - WITHOUT F-STRINGS
name = 'Bob'
age = 12
print('This is ' + name + ', he is ' + age + ' years old.')
# NEW - WITH F-STRINGS
print(f'This is {name}, he is {age} years old') # Note the f in frontSource: www.codegrepper.com
