Question

create three plots within a single graph, namely a plot, a scatter, and a bar superimposed on over the other. x-axis indices beginning with 1 and y-axis are grades that were entered by using an infinite loop

in python

Answer 1

A for loops allows us to execute a block of code multiple times with some parameters updated each time through the loop .A for loop begins with the for statement:

iterable=[1,2,3]

for item in iterable:

# code block indented 4 spaces

print(item)

1

2

3

The main points to observe are:

for and in keywords

iterable is a sequence object such as a list, tuple or range

item is a variable which takes each value in iterable

ends for statement with a colon:

code block indented 4 spaces which executes once for each value initerable

For example ,let's print n*2 for n from 0 to 5:

for n in [0,1,2,3,4,5]:

square=n**2

print(n,'squared is ',square)

print('The for loop is complete!)

0 squared is 0

1 squared is 1

2 squared is 4

3 squared is 9

4 squared is 16

5 squared is 25

The for loop is comlete!
