f format string 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: python fstring

#python3.6 is required
age = 12
name = "Simon"
print(f"Hi! My name is {name} and I am {age} years old")

Example 3: python f string literal

# This answer might be long, but it explains more python f-strings, how to use them and when to use them.
# Python f-strings are used to write code faster.
# Here is an example:
name = "George"
age = 16
favorite_food = "pizza"

# Instead of doing this:
print("My name is", name, ", my age is", age, ", and my favorite food is", favorite_food)

# Or this:
print("My name is "+ name +", my age is "+ str(age)+ ", and my favorite food is "+ favorite_food)

# You could do this:
print(f"My name is {name}, my age is {age}, and my favorite food is {favorite_food}")

# You see that the code looks a little cleaner, and as you start using f-strings you realize you write much faster.
"""
Why put the f before the string, you ask?
Well if you didnt, the output would literally be {name} instead of the actual variable
One more thing: this is fairly new and only works with python 3.6 and higher.
