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 Smithpython f string
>>> name = "Eric"
>>> age = 74
>>> f"Hello, {name}. You are {age}."
'Hello, Eric. You are 74.'python f string
"""
An f-string stands for 'function-string' it's just used to work with
strings more appropiately, they do the exact same job as concantenating
strings but are more efficient and readable.
"""
# Concantenating strings:
Age = "25"
print("I am "+Age+" years old.")
# Using f strings:
Age = 25
print(f"I am {Age} years old.")
# ^ notice the letter 'f' at the begining of the string.
# That defines the string as being an f-string.
# A third way of inputting variables into a string is by using
# .format()
Age = "25"
print("I am {} years old.".format(Age))
# If you had more than one variable:
Age = "25"
Name = "Jeff"
print("I am {} years old, and my name is {}.".format(Age,Name))python f string
>>> name = "Eric"
>>> age = 74
>>> f"Hello, {name}. You are {age}."
'Hello, Eric. You are 74.'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_valuepython 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!!Copyright © 2021 Codeinu
