This week we will investigate how to work with for loops and while loops in Python. We use iteration (loops) to prevent typing the same code out many times and to make our code more efficient. There are two main types of loop: Count Controlled: used to repeat a group of statements a set number of times – a for loop is an example.

When the statement executes, it iterates once for each item in the sequence. The general format is as follows: for variable in [value1, value2, etc.]: statement. statement. etc. Using the range function

Languages in the C family (including C++, Java, Perl, and Python) count from 0 because that’s more convenient when indices are computed rather than constant. As a result, if we have an M×N array in Python, its indices go from 0 to M-1 on the first axis and 0 to N-1 on the second. It takes a bit of getting used to, but one way to remember the ...
