Let’s discuss a few ways to solve this particular problem. But the problem of converting the entire list of strings to integers is quite common in the development domain. Some values in the input list can't be converted to int. Courses Practice Interconversion between data types is facilitated by python libraries quite easily. Print("Some values in the input list can't be converted to int.") To handle exceptions so that the program doesn’t terminate abruptly, you can use python try-except blocks as shown below. It may result in loss of data or work done in your program. List type method sort() sorts the original list Built-in function sorted() return. Due to this, the program runs into a ValueError exception.Įxceptions cause a program to terminate abruptly. This operator is referred to as the Python string concatenation operator. In the above example, the string ‘ Aditya‘ cannot be converted into an int. ValueError: invalid literal for int() with base 10: 'Aditya' Output: Traceback (most recent call last):įile "/home/aditya1117/PycharmProjects/pythonProject/string12.py", line 2, in You can observe this in the following example. Therefore, it is possible that the program may run into the ValueError exception if we find an element in the list that cannot be converted into an integer. This approach doesn’t check if the string can be converted into an int or not before calling the int() function. You can use list comprehension instead of for loops to convert a list of strings to a list of ints as shown below. List comprehension in python is used to create new lists from existing container objects. Convert a List of Strings to Integers Using List Comprehension Hence, it has been omitted from the output. In the above example, the string ‘Aditya’ cannot be converted into an int. 'Aditya' cannot be converted into an integer. Print("data type of ' cannot be converted into an integer.".format(element)) The int() function takes a string or a floating-point literal as its input argument and returns an integer as shown below. The join () function combines the elements of a list using a string separator.
