A few weeks ago we talked to you about the Predefined functions in Python<\/a>, are those that they come integrated <\/strong>and they help us list, add, print on the screen, etc.<\/p>\n\n\n\n

But sometimes we're going to need a function to do something specific<\/strong> outside of the predefined ones and we will have to create it ourselves, so let's see how it is done.<\/p>\n\n\n\n

Remember that you can continue learning about programming, in  EIP<\/a> with our master in Advanced Programming in Python for Big Data, Hacking and Machine Learning<\/a>.<\/p>\n\n\n\n

Create a function in Python<\/h2>\n\n\n\n

To create a function we start from the instruction def<\/em><\/strong>, <\/em>Let us remember that this word is included within the Keywords<\/a> of Python, followed by the name of the function and ending it with a colon ' :<\/strong> '.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

For example, we are going to make our first function print the typical "Hello World"<\/strong><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

First we define in the function a print<\/strong> with Hello World and then we invoke it to print the message, remember that if the function is not called it will never do anything.<\/p>\n\n\n\n

We can also make that function return <\/strong>a data to later assign it to some variable.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Finally, so as not to extend ourselves, we are going to see the functions with parameters<\/strong>, these functions receive parameters that we have previously defined to execute the corresponding code.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

The parameters that our function receives can be any type of data, numbers, letters, lists, etc. But we will see that another time.<\/p>\n\n\n\n

Next week we will use what we learned to update our Calculator in Python<\/a> and make it a little more efficient.<\/p>","protected":false},"excerpt":{"rendered":"
