Withre.split, we can split strings by using regular expressions. re.split(pattern, string, maxsplit=0, flags=0) The method gives us more powerful options to cut strings. reg_split.py #!/usr/bin/python import re line = "sky, \nclub, \tcpu; cloud, \n\n\nwar; pot, rock, water...
>>> str.strip('n') #删除字符串首尾匹配的字符,通常用于默认删除回车符 'string lEAR' >>> str.lstrip('n') #左匹配 'string lEARn' >>> str.rstrip('n') #右匹配 'string lEAR' >>> str = " tab" >>> str.expandtabs() #把制表符转为空格 ' tab' >>> str.expandtabs(2) #...
>>> 'www.example.com'.strip('cmowz.') 'example' Changed in version 2.2.2: Support for the chars argument. str.swapcase() Return a copy of the string with uppercase characters converted to lowercase and vice versa. For 8-bit strings, this method is locale-dependent. ...

rstrip() - 右边清洗 弄清楚了一个,另外两个自然清楚,我们以方法strip()演示。默认情况下,方法strip()会处理掉字符串两边的\t\n\r\f\v等空白符号。 >>>intf='\r\ninterface GigabitEthernet10/0/3\n'>>>intf'\r\ninterface GigabitEthernet10/0/3\n'>>>print(intf)interfaceGigabitEthernet10/0/3>>...
当需要构建大量字符串时,列表推导式结合join()方法通常比循环更高效: # 不推荐的方式 numbers = range(10) strings = [] for num in numbers: strings.append(str(num)) # 推荐的方式 strings = [str(num) for num in numbers] result = " ".join(strings) 在微服务架构和实时数据处理中,高效的字符串...
