Variables in Python [Explained]

Create variables in python

• There is no command or specific syntax for variables in python.

• Variables are created when you assign a value to it:

a = 5
b= 2
c = "Hello, World!"

print(a)
print(b)
print(c)

• You don’t need to specify the type of the variable before assigning it.

• In the example above ‘a’ variable is an integer and ‘c’ is a string and both are assigned in the same way.
  
  

Assign type to variable in python

you can assign a data type to a variable in python like this:

x = str(3)    # string 
y = int(3)    # integer
z = float(3)  # float , it's basically converting from integer to float.

Get the type of a variable in Python:

x = str(3)   
y = int('3')    

print(type(x))
print(type(y))

Output:

<class 'int'>
<class 'str'>
