[python] The method of judging whether it is an integer: 1. Use the [type()] function to judge, the code is [type(name, bases, dict)]; 2. Use the [isinstance()] function to judge, the code is [isinstance( object, classinfo)].
The operating environment of this tutorial: windows7 system, python3.9 version, DELL G3 computer.
Python's method of determining whether it is an integer:
1. Use the type() function to judge
type()Function syntax:
|
1
2
|
type(object)
type(name, bases, dict)
|
The type() function returns the type of the object if you have only the first parameter, and the new type object for three parameters.
Example:
|
1
2
|
>>> type(``1``)
<type ``'int'``>
|
2. Use the isinstance() function to judge
isinstance()Method syntax:
|
1
|
isinstance(object, classinfo)
|
Returns True if the type of the object is the same as the type of the second parameter (classinfo), otherwise returns False.
Example:
|
1
2
3
|
>>>a = ``2
>>> isinstance (a,int)
True
|
