This article will explain how to use recursion in Python functions, with some example code to illustrate the concept. A recursive function is a function which calls itself one or more times until a condition is met. If a function that uses recursion calls itself too many times, Python will throw an error. As this is a demonstration of a code structure rather than anything with any specific syntax, I’ll show a simple example of a recursive function and leave comments explaining what is going on.

This tutorial covers converting Bytes to a string variable (and a string to Bytes) in Python versions 2 and 3. What is the difference between a string and a byte string? A string is a series of characters. When stored on disk, the characters are converted to a series of bytes. What series of bytes represents what character is defined by the character encoding. When a string is stored to disk, it is converted to bytes (encoding). When it is read back into a program, the bytes must be converted back to a … Read more

This article explains how to check the type of a variable in the Python programming language. What are Types? The type of a variable determines what it can or can’t do. It determines what value the variable may take and what can be done with that value. Using the type() Function Pass a variable or value to the type() function, and the variable’s type will be returned: myNumber = 4 type(myNumber) # int myString = ‘foo’ type(myString) # str Using the isinstance() Function For more examples, check out the similar isinstance() function: To compare the … Read more
