_ variable in python

"""Use of _ as a variable
It is to indicate throwaway variables, 
...i.e. variables that are not reused anywhere else (as they are...
        ...not logically important) but for syntax reasons you have to put

This saves space for variables that are actually reused...
...and provides a good mental model for essential and unessential parts...
...of your code

Of course, take this as a guideline. 
There are instances where naming those variables are better for readability...
...especially in group projects

python declare a variable

# in python you can declare a variable by simply typing the variable name and assigning a value to it, no keywords needed. like so:

variable_name = 'value'

# there are 4 types of values you can store in python, just like most languages.

# a string: 'Helo word!'
# an integer: 1010001
# a float: 1010101.7
# and last, a boolean: True or False

# when you have declared a variable you can call it by simpely typing its name

print(variable_name)

# happy coding!

how to create a variablein python

#to create a variable in python:

var = 15 #var is the variable name and 15 is it's value
print(var) #prints the variable var's value

var2 = var + 15 #creating a new variable and value is var + 15
print(var2) #prints var2 which would be 30

# By Codexel

How to write variables in python
