当我打印文本时，文本和大量空白之间存在巨大差距，是否有一种有效且简单的删除它们的方法？ 例如， 这里有很多空白行，我想删除它们吗？

Answer 1

您可以随时尝试：

your_string.replace(" ","")

这将删除所有空格，包括前导和尾随空格

Answer 2

您可以尝试删除每个字符串中的，'' 部分，因为在字符串中添加 '' 只会在 output 中添加一个空格。

Answer 3

为什么不使用条带？

#...The most simple example 

txt = "     hamburgers    "

x = txt.strip()

print("I like", x, ".They are my favorites")

output 将是整个字符串本身，但没有空格。 strip 消除了字符串开头和结尾的所有指定空格。 您也可以将其与其他字符串一起使用

假设 txt 是：

txt = ']hamburger]'
x= txt.strip(']')

如果你打印 x 你会得到 'hamburger'
