#======================================================================================
#                               VARIABLES
#--------------------------------------------------------------------------------------
# A variable is a name you create to store a value, so you can use it later in your code
# You can think of a variable as container that holds information
#======================================================================================

#--------------------------------------------------------------------------------------
# Creating a variable
#--------------------------------------------------------------------------------------
x = 20      # Here x is a variable and 20 is its value
print(x)

#--------------------------------------------------------------------------------------
# updating variable x's values to 30
#--------------------------------------------------------------------------------------
x = 30
print(x)

#--------------------------------------------------------------------------------------
# Creating New variable y with value as x + 10
#--------------------------------------------------------------------------------------
y = x + 10
print(y)
print()

# Use Cases
print("My Name is Alice")
print("Alice is learning Python")
print("Alice wants to become python expert\n")

print("My Name is Frank")
print("Frank is learning Python")
print("Frank wants to become python expert\n")

#--------------------------------------------------------------------------------------
# To Make code dynamic we use variables
# Variables make updates super easy(one change updates everything)
#--------------------------------------------------------------------------------------
name = "BOb"
language = "Python"
print("My Name is", name)
print(name, "is learning", language)
print(name, "wants to become", language, "expert\n")

# Summary of Variables

# Make program dynamic
# Name to store a value
# Stored in memory
# Reusable anytime
# Updatable anytime
