python template literals 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: template string python

print("Hello {planet}".format(planet='World'))

#or 

i = "Hello"

print("{word} World".format(word= i ))

Example 3: new python string formatting

>>> f'Hello, {name}!'
'Hello, Bob!'

Example 4: string template python

from string import Template
poem = Template('$x are red and $y are blue')

print(poem.substitute(x='roses', y='violets'))
#>>>roses are red and violets are blue
