Example 1: python fstring
#python3.6 is required
age = 12
name = "Simon"
print(f"Hi! My name is {name} and I am {age} years old")
Example 2: 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))
Example 3: python string format
string_a = "Hello"
string_b = "Cena"
# Index based:
print("{0}, John {1}"
.format(string_a, string_b))
# Object based:
print("{greeting}, John {last_name}"
.format(greeting=string_a, last_name=string_b))
Example 4: str.format python 3
print("Sammy the {pr} {1} a {0}.".format("shark", "made", pr = "pull request"))
Example 5: python format strings
name = "Rick"
age = 42
print(f"My name is {name} and I am {age} years old")
