Answer 4

To calculate π to a specific number of decimal places in Python, you can use the mpmath library, which supports arbitrary-precision arithmetic.Here is an example code

from mpmath import mp

def calculate_pi(decimal_places):

mp.dps = decimal_places + 1 # +1 to account for the integer part of pi

pi_value = mp.pi

return str(pi_value)

decimal_places = int(input("Enter the number of decimal places: "))
print(calculate_pi(decimal_places))
