如何在Python3中多行打印长字符串

Question

我最近遇到了 python f-string。让，有一长串像

string = 'L4qrGFHK8eDA9Vy05gNH7inxfaVpPZH3i9pRdWScalA0pIGHKGqUEXejplKiYaCNizbiKH72LoQaoz1pQH9caDfAX5xtfQAZEri7QGkvxMAJWXsjPEPLQhTtTvvhDR1tMM9zX8Dd0l15bBW1Q3VQReOsbP5AQmMOK9GV0WYPZ015sg7tg8JKOs7hFJfD8bdpUQgWbGrxSdS95PnBTf4P2nTWWLrWzo3DQNyXHs29R6MZ92qqfPLGL8SSQNchWyo4V9NoHdAHDo5TdPf6VmNQaQAl9HKLVawTTg379plHr81YYEoojzstCSPh3jAy9W4dmjTLrBUxzA9tK5UlHKMGx7IYieNGfXBKTaCegdJOUubZPajkp0KY8OcpHxlaVFVdIPi58n6VH7evAomB'

我想像这样打印这个字符串：

L4qrGFHK8eDA9Vy05gNH7inxfaVpPZH3i9pRdWSc alA0pIGHKGqueXejplKiYaCNizbiKH72LoQaoz1p QH9caDfaX5xtfQAZEri7QGkvxMAJWXsjPEPLQhTt TvvhDR1tMM9zX8Dd0l15bBW1Q3VQReOsb P5AQmMO K9GV0WYPZ015sg7tg8JKOs7hFJfD8bdpUQgWbGrx SdS95PnBTf4P2nTWWLrWzo3DQNyXHs29R6MZ92qq fPLGL8SSQNchWyo4V9NoHdAHDo5TdPf6VmNQaQAl 9HKLVawTTg379plH r81YYEoojzstCSPh3jAy9W4d mjTLrBUxzA9tK5UlHKMGx7IYieNGfXBKTaCegdJO UubZPajkp0KY8OcpHxlaVFVdIPi58n6VH7evAomB

我想使用 F 弦。我尝试过左对齐

print(f"{string}:<{40}")

但它不起作用。

Answer 1

这就是您使用 textwrap 的目的：

import textwrap
string = 'L4qrGFHK8eDA9Vy05gNH7inxfaVpPZH3i9pRdWScalA0pIGHKGqUEXejplKiYaCNizbiKH72LoQaoz1pQH9caDfAX5xtfQAZEri7QGkvxMAJWXsjPEPLQhTtTvvhDR1tMM9zX8Dd0l15bBW1Q3VQReOsbP5AQmMOK9GV0WYPZ015sg7tg8JKOs7hFJfD8bdpUQgWbGrxSdS95PnBTf4P2nTWWLrWzo3DQNyXHs29R6MZ92qqfPLGL8SSQNchWyo4V9NoHdAHDo5TdPf6VmNQaQAl9HKLVawTTg379plHr81YYEoojzstCSPh3jAy9W4dmjTLrBUxzA9tK5UlHKMGx7IYieNGfXBKTaCegdJOUubZPajkp0KY8OcpHxlaVFVdIPi58n6VH7evAomB'
# print("{string}:<40")
print(textwrap.fill(string, 40))
