Strings can beconcatenatedto build longer strings using the plus sign and also they can bemultipliedby a number, which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen...

1. Can we convert a string to a list in Python? Yes, you can convert a string to a list using methods like split(), list comprehension, or json.loads(). For example, using split(): string = "apple,banana,cherry" list_of_fruits = string.split(",") print(list_of_fruits) # Outp...
整个re.findall(r'GigabitEthernet', output)返回的是一个包含了所有GigabitEthernet的列表,简单点来说,你可以把它当成Excel里面的“查找所有”功能。随后我们并将该正则表达式查找的内容赋值给self.number_of_up_port,(self.search_up_port = re.findall(r'GigabitEthernet', output))...
这里我们先将'192.168.1.0'赋值给floor1这个变量,再对该变量调用split()这个方法,然后将返回的值赋值给另外一个变量floor1_list,注意这里split()括号里的'.'表示分隔符,该分隔符用来对字符串进行切片,因为IP地址的写法都是4个数字用3个点'.'分开,所以这里分隔符用的是'.',因为split()返回的值是列表,所以这里...
