如何从Python中删除字符串末尾的空格？

Question

我需要删除字符串中单词后面的空格.这可以在一行代码中完成吗？

例:

string = "    xyz     "

desired result : "    xyz" 

Answer 1

>>> "    xyz     ".rstrip()
'    xyz'

Answer 2

您可以使用 strip() 或 split() 来控制空格值，如下所示，这是一些测试函数：

words = "   test     words    "

# Remove end spaces
def remove_end_spaces(string):
    return "".join(string.rstrip())

# Remove first and  end spaces
def remove_first_end_spaces(string):
    return "".join(string.rstrip().lstrip())

# Remove all spaces
def remove_all_spaces(string):
    return "".join(string.split())

# Remove all extra spaces
def remove_all_extra_spaces(string):
    return " ".join(string.split())

# Show results
print(f'"{words}"')
print(f'"{remove_end_spaces(words)}"')
print(f'"{remove_first_end_spaces(words)}"')
print(f'"{remove_all_spaces(words)}"')
print(f'"{remove_all_extra_spaces(words)}"')

输出：

"   test     words    "

"   test     words"

"test     words"

"testwords"

"test words"

我希望这有帮助。
