In Python, an array is a special variable that allows you to store multiple values in a single variable. This powerful feature is frequently used in data analysis, data science, and in general programming tasks.
In order to assess the values of an array, we often need to print it out. One of the methods to print an array in Python is by using a for loop. In this tutorial, we will explain how you can print an array in Python by using a for loop.
Getting Started
Before we begin, make sure you have Python installed on your system. If you haven’t installed Python yet, you can download it from the official Python website.
Step 1: Create an Array
To begin with, we first need to create an array. In Python, this can be done with a simple list.
|
1 |
array = ['Hello', 'Python', 'World'] |
We have created an array with three elements: ‘Hello’, ‘Python’, and ‘World’.
Step 2: Print the Array Using a For Loop
Once the array is created, we can print it using a for loop. Here is how you can do it:
|
1 2 |
for element in array: print(element) |
This for loop will iterate over each element in the array and print it.
Seeing the Output
After running the script, you should see this output:
Hello Python World
The Complete Code
Here’s the complete code:
|
1 2 3 4 |
array = ['Hello', 'Python', 'World'] for element in array: print(element) |
Conclusion
Printing an array using a for loop in Python is a fundamental skill that every beginner should learn. It’s a standard way to iterate over an array’s elements and can be used to form more complex structures and logic later. This efficient method condenses the process into a neat and compact procedure, saving time and reducing the potential for errors. Happy coding!
