Get the Index of the Symbol

To find the index of a specific symbol or substring in a string, Python provides the built-in .find() method. This method returns the index of the first occurrence of the substring. If the substring is not found, it returns -1.

string.find(substring)

Here, string is the original text, and substring is the character or sequence you want to locate.

string = "Channel efforts to success!"

print(string.find('n'))


              12
            
string = "Channel efforts to success!"
print(string.find('n'))

In the string "Channel efforts to success!", the first 'n' appears at index 3. So, the find() method returns 3.

If the character were not found, for example, string.find('z'), the result would be -1.
