The ___ function is used to determine the type of a variable in Python. The ___ function can be used to check if a variable is of a specific type in Python. If we want to check the type of a variable `x`, we
You can also use the isinstance() function to check if a variable is an instance of a particular type. For example:x = 5 print(isinstance(x, int)) # Output: True print(isinstance(x, str)) # Output: False y = 'hello' print(isinstance(y, str)) # Output: True print(isinstance(y,...
2. Use type() to get Python Variable Type The Pythontype()is abuilt-in functionthat finds the data type of a variable. It takes a variable as an argument and returns the type of the variable. This function is useful when you want to check thedata typeof a variable or perform certain...
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 object is a specified type otherwise it returns False....
Objective: This article will discuss the different methods to check if a variable exists in Python. Before we dive into the methods to check for the availability of a variable in the code, let us first understand why we need to do so? 🤔 To answer the above question, you must understan...
local scope will change global variable due to same memory used input: importnumpyasnpdeftest(a):a[0]=np.nanm=[1,2,3]test(m)print(m) output: [nan, 2, 3] Note python has this really weird error if you define local variable in a function same name as the global variable, program...

To achieve our goal, we’ll use theindexmethod which is a function associated with a specific class and serves for a certain function when attached to a variable following a dot. Theindexmethod in particular, returns the index of the given substring, inside the string.The substring that we ...
