1. Using type(object) Method to Check Data Type in Python In this example, we will be taking the input in all the forms to write the variable like string, integer, negative value, float value, complex number, list, tuple, set, anddictionary. After that, we will print the data type ...
In this article, we are going to find out how to check if the type of a variable is a string in Python.The first approach is by using the isinstance() method. This method takes 2 parameters, the first parameter being the string that we want to test and the next parameter is the ...
Checking global variable To check if a global variable exists or not in Python, we can use the built-in globals() function. Example: fruit = "apple" if 'fruit' in globals(): print ("fruit variable exist") else: print ("fruit variable does not exist") Output: "fruit variable exist...

'Variable is not a tuple' Using isinstance() function Similarly, we can also use theisinstance()function in Python to check if a given variable is tuple. Theisinstance()function takes the two arguments, the first argument isobject, and the second argument istypethen It returnsTrueif a given...
andFalseif they are not. You can use the==operator to compare values of any type, including integers, floats, strings, and objects. In the below example, I am using it with a string variable and comparing it with the empty string"", similarly, you can also use it with string literals...

The equality operator == is another way to check if variable is None in Python, but it is not recommended. Using the is keyword 1 2 3 4 5 x = None if(x == None): print("x is of the 'None' type.") Output: x is of the ‘None’ type. The == operator checks whether ...
PyChecker是Python代码的静态分析工具,它能够帮助查找Python代码的bug,而且能够对代码的复杂度和格式等提出警告。 PyChecker可以工作在多种方式之下。首先,PyChecker会导入所检查文件中包含的模块,检查导入是否正确,同时检查文件中的函数、类和方法等。 PyChecker可以检查出来的问题有如下几种: ...
