How to Remove Data From an Array in Python

Arrays are necessary for programming applications that contain several values that must be used to make calculations for user output. Python offers two types of array value removal functions. The first one removes a value based on the value name. The second function removes a value based on the index number. You use both of these functions to remove data from an array that you do not need in your calculations.

Instructions

1. Open the Python editor you want to use to edit the source code file. Open the source code file to load the existing code in the editor.

2. Remove an array value using the "remove" function. This function takes a value as the parameter, and the first instance of that value is removed from the array. The following code removes the value "myvalue" from the array "myarray":

   myarray.remove("myvalue")

3. Remove an array value using the value's index. Each value is assigned an index number starting at the number zero. The following code removes any value located at the index "1":

   myarray.pop(1)
