Question

Using Python:

Write a program that takes a user-inputted integer and prints out the value of pi to the number of decimal places specified by the integer. For example, if the inputted integer is '2' your program should print '3.14'.

Hints:

• Python's math package includes a constant for pi (as pi). We have imported pi for you in the example code below.
• The format string syntax for rendering a floating point value to N decimal places is {:.Nf}. The example code below prints pi to 10 decimal places.
• You will first need to assemble a format string, and then print your result using that format string.

SAMPLE CODE:

from math import pi

# Example input() statement
n = int(input('Please enter an integer: '))

format_string = '{:.10f}'

# Replace this with your own print statement
print(format_string.format(pi))

Answer 1

from math import pi                   #importing math function
n=int(input())                        #input for n decimals
format_string='{:.{}f}'               #assigning pi value to format_string upto n decimals
print(format_string.format(pi,n))     #printing pi value to format_string upto n decimals
