以上只是我学习strip函数时的所想所思,根据我的这个想法,我自己写了一个与strip有相同用法的函数 defreplace_fun(s_1, s_2):''':param s_1: 移除字符串头尾指定的字符序列 :param s_2: 原字符串 :return: 返回移除字符串头尾指定的字符生成的新字符串'''foriins_2:ifiins_1: s_2=
def replace_fun(s_1, s_2): ''' :param s_1: 移除字符串头尾指定的字符序列 :param s_2: 原字符串 :return: 返回移除字符串头尾指定的字符生成的新字符串 ''' for i in s_2: if i in s_1: s_2 = s_2.replace(i, '', 1) else: break for i in s_2[::-1]: if i in s_1:...
输出结果分别为 python is fun 、 python is fun 和 python is fun。可以看出,lstrip 只移除 了开头的空格,rstrip 只移除了结尾的空格,而 line.strip 则同时移除了首尾的空格。在实际应 用中,如果只需要处理字符串开头或结尾的特定字符,lstrip 和 rstrip 会更加适用;若需要同 时处理首尾字符,则 line.strip 更...

To control the LED strip we use a Python library fromAdafruit. This special Raspberry Pi WS2801 library includes some functions for controlling the individual LEDs. The good thing is that each LED can be addressed individually and anyRGB coloris possible. ...
might seem overkill, but as it turns out, [MacCraiger] has actually added in quite a bit of extra functionality. The purists might say it still could have been done with an ESP8266, but being able to toss some Python scripts on the Linux computer inside your clock certainly has its ...
