Suppose you need to take out word(s) instead of characters from string. Generally we consider one blank space as delimiter to find words from string. 1. Find first word of string mystring.split()[0] Output 'Hey' How it works? split()function breaks string using space as a default sepa...
如果找到了字符串"Python",则find方法会返回第一次出现这个字符串的位置。 如果没有找到,则返回 -1。 find函数默认从第一个字符开始搜索,也可以从第n个字符开始,如下所示: str = "welcome to Python" print(str.find("Python",12)) 1. 2. 因为我们从第12个字符开始,所以找不到 Python 这个单词,所以它...
