The following is the code to check if all elements in a list are integers or not. # check if all elements in ls are integers all([isinstance(item, int) for item in ls]) Let’s take a look at an example. # list of numbers ls = [1, 2, 3, 4] # check if list contains only numbers print(all([isinstance(item, int) for item in ls])) Output: True We get Let’s take a look at another example. # list of numbers and a string ls = [1, 2, 3, 4, 'cat'] # check if list contains only numbers print(all([isinstance(item, int) for item in ls])) Output: False Here we get Check if all items in a list of strings are numericIf you, however, have a list of strings and want to check whether all the elements in the list are digits or not, you can use the following code. # list of numeric strings ls = ["1", "2", "3", "4"] # check if list of string contains only numberic elements print(all([item.isdigit() for item in ls])) Output: True Here we check whether each element in the list of

How do you check if an integer is present in a list?We can use the in-built python List method, count(), to check if the passed element exists in the List. If the passed element exists in the List, the count() method will show the number of times it occurs in the entire list. If it is a non-zero positive number, it means an element exists in the List.
How do you find the number in a list in Python?The most straightforward way to get the number of elements in a list is to use the Python built-in function len() . As the name function suggests, len() returns the length of the list, regardless of the types of elements in it.
