How to add X number of spaces to a string
提问by Mitch
Probably an easy question that I couldn't quite find answer to before...
可能是一个简单的问题，我以前找不到答案......
I'm formatting a table (in text) to look like this:
我正在格式化一个表格（在文本中），如下所示：
Timestamp: Word Number
The number of characters between the : after timestamp and the beginning of Number is to be 20, including those in the Word (so it stays aligned). Using python I've done this:
: 时间戳之后和 Number 开头之间的字符数为 20，包括 Word 中的字符数（因此它保持对齐）。使用 python 我已经做到了：
offset = 20 - len(word)
printer = timestamp + ' ' + word
for i in range(0, offset):
printer += ' '
printer += score
Which works, but python throws an error at me that i is never used ('cause it's not). While it's not a huge deal, I'm just wondering if there's a better way to do so.
哪个有效，但是 python 向我抛出一个错误，我从未使用过（因为它不是）。虽然这不是什么大问题，但我只是想知道是否有更好的方法来做到这一点。

Since I can't add an answer to this (as it's marked duplicate) the better way to replace this whole thing is
由于我无法对此添加答案（因为它被标记为重复），因此替换整个事情的更好方法是
printer = timestamp + ' ' + word.ljust(20) + score

You can multiply by strings by numbers to replicate them.
您可以将字符串乘以数字来复制它们。
printer += ' ' * offset

Try
尝试
printer += ' '*offset
instead of the for-loop
而不是 for 循环

String formatting may work too
字符串格式也可以工作
'{}: {: <20s}{}'.format("Timestamp", "Word", 200)
Timestamp: Word 200
