stringexample.find("ki") The output for this will be0. The reason behind the output is – this method returns the lowest index value when the substring is found. If it returns-1that means the string does not contain that substring. ...
In this example, we attempt to find the substring “New York” within thetextstring. If “New York” is found, its starting index is printed. If it’s not found, the code catches theValueErrorexception and prints a message indicating that the substring is not present in the text. ...

print(str.__contains__('ABC', 'D')) Output: Let’s look at another example where we will ask the user to enter both the strings and check if the first string contains the second string or substring or not. input_str1 = input('Please enter first input string\n') ...
>>> re.findall("abc\b","asdas abc") []>>> re.findall(r"abc\b","asdas abc")#"r"使"\b"为含有特殊意义的字符['abc']>>> re.findall(r"\bI","IMISS IOU")#匹配出单词左边的"I"['I','I']>>> re.findall(r"I\b","IMISS IOU")#匹配出单词有边的"I"[] ...
