Project Euler Problem 13

tot = 0
with open('pe13.txt') as file:
    lines = file.readlines()

lines = [x.strip() for x in lines]

for x in range(0, len(lines)):
    line = lines[x]
    tot += int(line)


tot = str(tot)
tot = tot[:10]
print(tot)

Above is what I first did to solve the problem. Below is how I refined my solution:

tot = 0lines = []

with open('pe13.txt') as file:
    lines = file.readlines()

lines = [x.strip() for x in lines]

lines = list(map(int, lines))

tot = str(sum(lines))
tot = tot[:10]
print(tot)

and even more:

with open('pe13.txt') as file:
    lines = file.readlines()

lines = [x.strip() for x in lines]
lines = list(map(int, lines))

print(str(sum(lines))[:10])

Quite compact if I may say so.
