What is wrong with this code? It is supposed to give the value of the Nth digit of Pi which the user provides.

Answer 1

if you mean your code:

22/7 is just an aproximation of pi.
It is correct only up to 3.14. The rest will always be incorrect. Pi is an irrational number. You cannot use such a simple fraction to calculate the digits.

a = 22
b = 7

# actual value only looks like pi for the first 3 digits
print(f'{a/b = }')
digits = [0]

#using your formula will not give correct value of pi after 3.14.
for n in range(0,50):
print(f'{n = } -> {digits[-1] = }')
while len(digits) < n:
c = 0
d = a % b
while a >= b :
a = a - b
c += 1
digits.append(c)
a = d * 10
