我有几行整数(来自.txt文件),我想为每一行逐一求和每个符号整数。
示例:

答案 0 :(得分:2)
f = open('foo.txt', 'r')
def sum_line(line):
return sum(int(c) for c in line.strip())
line_sums = [sum_line(line) for line in f]
答案 1 :(得分:0)
你可以使用这样的东西来迭代文件的行并总结数字。
with open('file.txt', 'r') as f:
for line in f:
print(sum(int(char) for char in line.strip()))
如果您的行可能不是所有数字,则需要使用此代码进行检查。
print(sum(int(char) for char in line if char.isdigit()))
# no need for .strip() since \n characters are not a digit
