Converting a String to an Integer Array in Java. The general syntax looks something like this: int ("str"). Many operations like slicing, replacing, concatenation, etc. So, we can directly call the __str__() on the object. This function takes a string as input and returns its corresponding integer representation. This can be done by a list generator: li = ['1', '4', '8.6'] lst = [int(x) if x.isdigit() else float(x) for x in li] print(lst) To check if it actually worked, you can check for the types using another list generator: types = [type(i) for i in lst] print(types) Its used together with objects (including file objects) such as those produced with Pythons in-built open() function.
