For example: ["one", "two", "3"] would return false Yes. You can convert the string to a number and make sure that it raises an exception:

In this article we will dicuss different ways to check if all element in a given List are same or matches a condition. Suppose we have a list of string i.e. Now let’s use python all() function to check if all elements in the given list are same. Python all() function checks if all Elements
of given Iterable is True. Let’s convert the list to Iterable and check if each entry of iterable is equal to first element of list using all() i.e. Advertisements count() returns the occurrence count of given element in the list. Let’s call the count() function of list with firts element of list as argument. If its occurrence count is equal to the length of list, then it means all elements in
list are Same i.e. Let’s do the same thing in single line i.e. As set contains only unique elements, so convert the list to set. If set size is 1 then it means all elements in given list are same i.e. Complete example is as follows, Output: How do you check if all elements in a list are strings Python?Just use all() and check for types with isinstance() . @TekhenyGhemor - isinstance(item, str) and not item. lstrip('-'). isdigit() for zero or positive integers.
How do you check all items in a list Python?To check if the list contains an element in Python, use the “in” operator. The “in” operator checks if the list contains a specific item or not. It can also check if the element exists on the list or not using the list. count() function.
How do you check if all elements in a string are numbers?The 'all' operator is used to check if every element is a digit or not. This is done using the 'isdigit' method. The result of this operation is assigned to a variable.
How do you check if all elements in a list are numeric Python?Python String isnumeric() Method
The isnumeric() method returns True if all the characters are numeric (0-9), otherwise False.
