How To Create a List of Numbers from 1 to N in Python Using a User-Defined Function In Python, you can easily generate a list of numbers from 1 to N using a specified value by creating a user-defined function. This method involves defining a function that takes the desired number, iter...
In Python, we can use the range() function to create an iterator sequence between two endpoints. We can use this function to create a list from 1 to 100 in Python.The function accepts three parameters start, stop, and step. The start parameter mentions the starting number of the iterator...
