This article mainly shows you "Python how to achieve type checking", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "Python how to achieve type checking" this article.

Code implementation

A = 123# value b = '123' # string print (' a =', a) print ('b =', b) c = type ('123') print (c) c = type (a) print (c) print (type (b)) print (type (1)) # print (type (1.5)) # print (type (True)) # print (type (' hello')) # print (type (None)) #

Code run output:

A = 123

B = 123

# type () is used to check the type of value

# this function returns the result of the check as a return value, and you can receive the return value of the function through variables
