Numbers and strings
Python variables can store data of various allowed types. Some of the simplest data types are strings and integers (official names in Python are "str" and "int").
You can print the data type of a variable by using type() function (see example below):

#Example of a string variable
var = "42"
print(var)
print(type(var))
1234#Example of a string variable var = "42" print(var) print(type(var))
In the example above Python will print "42" and will treat this variable as a string.
In the example below it will also print "42", but will treat the variable as integer. You can only apply arithmetic operations to Numeric types (integer or others), not strings.
