[Python] NameError: name 'i' is not defined. How to solve this error? [closed]

When i run this code

from math import *
import matplotlib.pyplot as plt

N = 10
p0 = 0.8

p_dist = [factorial(N) / (factorial(N - k) * factorial(k)) * p0 ** k * (1 - p0) ** (N - k) for k in range(N + 1)]
# print(p_dist)
s = [sum(p_dist[:i + 1]) for i in range(len(p_dist))]
print(sum(p_dist))
print("i, p_dist, s")
for k in range(N + 1):
print(k, p_dist, s)

bar_width = 1
opacity = 0.8
rects1 = plt.bar(range(N + 1), p_dist, bar_width,
alpha=opacity,
color='b', )
plt.show()


I get the error
