nums=[4,5,6]iftype(nums)==tuple:print('Variable is tuple')else:print('Variable is not a tuple') Output: '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. ...
Python | Check if a variable is a string To check whether a defined variable is a string type or not, we can use two functions which are Python library functions, Using isinstance() Using type() Checking a variable is a string or not using isinstance() function ...
6.1 Filtering from the List 6.2 Filtering from the Dictionary 7. Conclusion In Python, Check if Variable Is None and Check if Variable Is null have same solutions as meaning of both queries is same. 1. Introduction In Python Programming, checking when a variable is None(Python equivalent of ...
y: This here can be any data type that you want to check the variable for. In our case, the value of this will be str. The following code uses the isinstance() function to check if a given variable is of the string type in Python. 1 2 3 4 5 var1 = "football" sol = isinst...
The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects...
This code snippet iterates over each element in the list, checks if it matches the target string "apple", and sets the found variable to True if a match is found, demonstrating a basic but effective way to check for the existence of an element in a Python list....
On each iteration, we check if the current value is contained in the original list. If the condition is met, we set theone_in_listvariable toTrueand exit the loop. Thebreakstatement breaks out of the innermost enclosingfororwhileloop. ...
A tuple is a built-in Python data structure for storing multiple items in a single variable. While both tuples and lists can organize ordered collections of items, tuples are immutable, whereas lists are mutable. A list can store heterogeneous values, including various types of data such as ...
odd_ids = [id for id in product_ids if is_odd(id)] print(odd_ids) Output: [105, 317, 531] This code filters theproduct_idslist only to include the odd IDs. Check outHow to Check if a Variable Exists in Python? Method 3. Use the bin() Function ...
