curly braces in python inside triple quotes code example

Example 1: f string repr

# If you want to use repr in f-string use "!r"
# Normal behavior (using str)
>>> color = "blue\ngreen"
>>> day = datetime.date(2020, 6, 4)
>>> f"Color is {color} and day is {day}"
'Color is blue\ngreen and day is 2020-06-04'
# Alternate behavior (using repr)
>>> f"Color is {color!r} and day is {day!r}"
"Color is 'blue\\ngreen' and day is datetime.date(2020, 6, 4)"

Example 2: str.format python 3

print("Sammy the {pr} {1} a {0}.".format("shark", "made", pr = "pull request"))
