It returns

Using find() to check if a string contains another substringWe can also use string find() function to check if string contains a substring or not. This function returns the first index position where substring is found, else returns -1.

What is the opposite of Contains in Python?If you are testing just for membership, i.e. does a list of values exist anywhere in the array then use isin this will also return a boolean series where matches are found, to invert the array use ~ .
