返回python中字符串的最后一个字符

Question

我想打印从文件中读取的python中字符串的最后一个字符.我打电话给str[-1]但不工作.

t.txt包含

Do not laugh please!        9

Are you kidding me?     4

我的代码是

with open('t.txt', 'r') as f:
    for line in f:
        print(line)
        print(line[-1])
        # break

但它不打印任何东西.

Answer 1

每行的最后一个字符是换行符.你可以剥掉它:

print(line.strip()[-1])  
# or print(line.rstrip()[-1])
