Searching a String

We also have the ability to search for substrings in strings using find() method. This method returns the index of the first occurrence of the substring. If there are no lines, then the function will return -1.

1234
string = 'Jackfruit, Coconut' position_1 = string.find('C') position_2 = string.find('c') print(f'The position of "C" is {position_1}, and the position of "c" is {position_2}')
copy

Don't forget Python is case sensitive. So, the first occurrence of the C is 11, and the first occurrence of the c is 2. Since C it is not the same as c.
