f string and format code example

Example 1: 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 2: 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!!
