通过remove_substring()函数,A向B发送了一个消息,请求去掉B所代表的子字符串。B处理完毕后,将结果返回给A。最后,A将结果传递给C进行打印输出。 结论 本文介绍了如何使用Python的字符串方法和正则表达式去掉另一个字符串。我们可以使用replace()方法替换字符串中的指定部分,也可以使用正则表达式的re.sub()函数进行替...
返回值 :runoob Python中类似sunbstring应用方法 python中没有substring的定义,但是有更轻巧的实现,可以通过数组的slice来截取字符串 例如,在java中我们这样截取字符串: String s = "Hello "; String small = s.subString(2,4); 而在python中,我们这样实现: s = "Hello " small = s[2:4] python的用法更...
my_string = "apple,banana,orange"result = my_string.split(",")print(result) # 输出 ['apple', 'banana', 'orange'] substring函数:这个函数用于截取字符串的子串,通过指定起始位置和结束位置来实现。它的语法是string[start:end],其中string是原字符串,start是起始位置(包含),end是结束位置(不包含)。截...
Note that find() function returns the index position of the substring if it’s found, otherwise it returns -1. Count of Substring Occurrence We can usecount() functionto find the number of occurrences of a substring in the string. s = 'My Name is Pankaj' print('Substring count =', s...
ValueError: substring not found >>> str.index("n") #同find类似,返回第一次匹配的索引值 4 >>> str.rindex("n") #返回最后一次匹配的索引值 11 >>> str.count('a') #字符串中匹配的次数 0 >>> str.count('n') #同上 2 >>> str.replace('EAR','ear') #匹配替换 'string learn' >...
