Python zfill() method stretches a string by adding zeros at the beginning. For instance, let’s add zeros to a string with zfill() until its length is 15: Output: This string is now 15 in length due to the zero-filling. If the length of the string is greater than what is passed into the zfill(), the […]

Here is a list of Python code examples. This list covers the basics of Python. You can use this list as a cheat sheet whether you are preparing for an exam, interview, or are otherwise curious about Python. Fundamentals of Python Variables A variable can store a value. The value can be a number, list,

The very basic Python example class is one with a name and a property. For instance: With this class, you can create weight objects and change their weights: Output: Let’s see some other useful class examples in Python. Python Class with Methods Example A super useful feature of classes is that you can add methods

Comparing values in code is one of the essential tasks you need to do all the time. In Python, there are six comparison operators in total. One of them, the not equal operator (!=) is the one you can use to check if a value doesn’t equal another. For instance: This is a comprehensive guide

You may be familiar with Swift operators, such as the + or – operators for adding and subtracting numbers. But did you know you can create completely new operators with customized meanings? For example, let’s create a completely new square root operator that works with the check mark emoji. This is a comprehensive guide that

A loop refers to a set of instructions that is repeated as long as a criterion holds. The two types of loops are for loops and while loops. Both can be described using a flowchart. For Loop Flowchart with an Example A for loop repeats statements as long as the last item in the range

In Python, a shallow copy is a “one-level-deep” copy. The copied object contains references to the child objects of the original object. A deep copy is completely independent of the original object. It constructs a new collection object by recursively populating it with copies of the child objects. Copying or Not In Python, you might use the = operator

Python enumerations or Enums can be used to couple related values together in a type-safe way. For example, here is an enumeration for directions: This makes it possible to call Direction.UP or Direction.DOWN in your program. Notice that Python enumerations have nothing to do with the enumerate() function. If you came for enumerate() check out this article. Python

To pick a random element from a list in Python, use the random module’s choice() method: Output (example): This provides you with a quick answer. However, there are other ways you can consider. Let’s take a deeper look at randomly picking elements from lists in Python. Random Element from a List in Python There are
