In this example a is greater than b, so the first condition is not true, also the elif
condition is not true, so we go to the else condition and print to screen that “a is
greater than b”. We can also use the else without using elif.
5.12. Loops in Python
A For loop is used for repeating over a sequence (that is either a list or a string). This
is less like the FOR keyword in other programming languages and works more like an
iterator method as found in other object-orientated programming languages.
For example, we have a list of students and we want to display the student with the Programming the Computer-Python
highest marks without using the max() function:
Sample Code
# This defines a list of student marks
stdMarks = [70, 80, 92.5, 60.2]
# This variable keeps track of the max marks
maxMarks = 0
# for loop block
for i in range(0,4):
if stdMarks[i] > maxMarks:
maxMarks = stdMarks[i]
# Prints highest student marks
print(“highest marks are: “, maxMarks)
