Check if Python StringContains SubstringUsing in operator The ‘in’ operator function in Python can check if a Python string contains a substring. This is the easiest way. It returns a boolean value, like true or false. Example: originalString = "pythonknowledge" ...
这里,我们创建了两个字符串:target_string是我们要检查的字符串,substring是我们要查找的部分。 2. 使用in运算符方法判断 in运算符是最简单且常用的方法之一,可以直接判断子字符串是否在目标字符串中。 # 判断 substring 是否在 target_string 中ifsubstringintarget_string:print(f"'{substring}' found in the ta...
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' >...
