How to Check Data Type of Variables in Python


In this article, you will learn how to check the data type of variables in Python.

Let’s say you have 5 variables.

# A variable named 'a' with value 123
a = 123

# A variable named 'b' with value "codesource"
b = "codesource"

# A variable named 'c' with value False
c = False

# A variable named 'd' with value ["red", "green", "blue"]
d = ["red", "green", "blue"]

# A variable named 'e' with value {"north", "south", "east", "west"}
e = {"north", "south", "east", "west"}

In order to check the data type of variables, you can use the type() method.

# A variable named 'a' with value 123
a = 123

# A variable named 'b' with value "codesource"
b = "codesource"

# A variable named 'c' with value False
c = False

# A variable named 'd' with value ["red", "green", "blue"]
d = ["red", "green", "blue"]

# A variable named 'e' with value {"north", "south", "east", "west"}
e = {"north", "south", "east", "west"}

print(type(a))
# => <class 'int'>

print(type(b))
# => <class 'str'>

print(type(c))
# => <class 'bool'>

print(type(d))
# => <class 'list'>

print(type(e))
# => <class 'set'>

Note: The type() method functions by returning the class type of supplied argument.
