![]() You may be interested in reading the following pages, which offer helpful information about this forum: However, this would raise a Synta圎rror: pin_number = 0276 The following would be valid: pin_number = "0276" Therefore, if your Python program contains a pin number, you should very likely enclose it in quotes. In many situations, valid pin numbers could begin with a 0. Most likely, that pin number should be thought of as a string, rather than as a number, even though it might consist entirely of digits. At a bank or on an electronic device, you may be asked for a pin number. Some entities that are commonly referred to as numbers are not actually numbers. Note that the strings are contained in either double or single quotes. However, if you were to specify the name of something, such as a programming language, you would most likely use a string, of which the following are examples: A count of some kind of object, such as a number of slices of pizza, would be appropriately expressed as an integer, such as 3. When writing a program, it is important to consider what types of data you are using. The following would not be accepted as integers by Python, because they each have a leading 0: Examples of integers, correctly expressed for Python, include: Some examples of types of numbers that can be used in Python programs are integers and real numbers. If you do post code, please make sure it is formatted correctly. If you had posted your code here, we could offer more effective help. Hello, and welcome to Python Foundation Discourse! If the zero was just a placeholder, then just remove it. If you intended it to be octal, then change it to use 0o. Read the error, and see which line of code it refers to.įind the number with a leading zero on that line of code. To write an octal number today, we write it as 0o1, and to avoid accidental mistakes the leading zero is prohibited. But that was confusing: too many people used a leading zero and then got the wrong result. In old versions of Python, we used 0123 to mean octal, giving the decimal value 83.
