How do you run a loop function in Python?

Syntax:

1. def function_name():
2. Statement1.

How do you iterate a function in R?

R has some functions which implement looping in a compact form to make your life easier.

1. lapply() : Loop over a list and evaluate a function on each element.
2. sapply() : Same as lapply but try to simplify the result.
3. apply() : Apply a function over the margins of an array.

How do I loop through a vector in R?

Instructions

1. A vector seq has been created for you.
2. Fill in the for loop, using seq as your sequence. Print out value during each iteration.
3. A variable sum has been created for you.
4. Use the loop to sum the numbers in seq . Each iteration, value should be added to sum , then sum is printed out.
