print(f ) python code example

Example 1: f string in python

# f-strings are short for formatted string like the following
# you can use the formatted string by two diffrent ways
# 1
name = "John Smith"
print(f"Hello, {name}")		# output = Hello, John Smith

# 2
name = "John Smith"
print("Hello, {}".format(name))		# output = Hello, John Smith

Example 2: 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 3: python f string

import random
name = input("What is your name? ") #Gets needed input
value = int(input(f"Give random value, {name}: ")) # The {name} means it puts the variable name there
multiplier = random.randint(3, 6)
print("Now multiplying your value...")
complete_value = multiplier * value
print(f"Your value is... {complete_value}") # Same here with complete_value

Example 4: python f string

>>> name = "Eric"
>>> age = 74
>>> f"Hello, {name}. You are {age}."
'Hello, Eric. You are 74.'

Example 5: python f string

# f-strings help in string concatenation
name = 'Psych4_3.8.3'
age = 23
job = 'programmer'

#USING OLD METHOD
print("I am %s a %t of age %u", %(name, job, age))

# USING F-STRING
print(f"I am {name} a {job} of age {age}")
# here you can even see whcih value is inserted in which place....
# the f means that it is an f string. DONT FORGET IT!!
