txt = "The rain in Spain stays mainly in the plain "
txt.strip()
輸出：
'The rain in Spain stays mainly in the plain'
stript()只是刪除開頭和結尾的空格，而不是字符串之間的空格。因此，以下陳述是正確的：
x = " " in txt.strip()
print(x)
輸出：
True
有很多方法可以刪除字符串中的所有空格：
1.split()
''.join(txt.split())
2.replace()
txt.replace(" ", "")
3、正則表達式：
import re
stringWithoutSpaces = re.sub(r"\s+", "", txt, flags=re.UNICODE)
所有這些的輸出是：
'TheraininSpainstaysmainlyintheplain'
