How to Make Variables in Python

# I’m starting this series to help me and hopefully you, learn python one snippets at a time.
# The series will contain short videos on how to's, for the python language. I’m aiming for one video a week, so let’s get started.
#
# If you don’t know already know variables are containers for storing data values.

# You can get away with a short variable names(like x and y) or a more descriptive and concise
# name (age, carname, total_volume).
# Rules for Python variables:
# • A variable name must start with a letter or the underscore character
# • A variable name cannot start with a number
# • Variable names are case-sensitive(age, Age and AGE are three different variables)

# # #Legal variable names:

# myvar = "John"
# my_var = "John"
# _my_var = "John"
# myVar = "John"
# MYVAR = "John"
# myvar2 = "John"

# #Illegal variable names:
# 2myvar = "John"
# my-var = "John"
# my var = "John"




# A data type is a type of data. Of course, that is rather circular definition,
# and also not very helpful. Therefore, a better definition of a data type is a
# data storage format that can contain a specific type or range of values.


#String = is a arrays of bytes representing unicode characters.
string_variable = "I'm a string"

#int = Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed!
integer_variable = 5

#float = Float is used to represent real numbers and is written with a decimal point dividing the integer and fractional parts
float_variable = 3.7


lary = "is a fish"
laryAge = 2
larysHouseSize = 10.5

print(f"who is lary, lary {lary}")
print(f"how old is lary is {laryAge}")
print(f"how big is lary's tank, lary's tank is {larysHouseSize} gollans big")


#you use the type() function to know which class a variable belongs to
# var = 5
# print(type(x))
