#Python #DataScience #String There are two functions that let you determine the positions of (the first occurrence of) a substring inside a string. Example:- text = "Data Science" Can you determine the position of "Sci" using both of the functions? …
#Solution
1. Using index() function we can determine the position of the first character of the substring in the string example: text.index("Sci") is 5.
2. The same thing we can use find() function
Example: text.find("Sci") is 5.

Note: the difference between these functions in how they deal with the situation when the substring is not contained in the string. For the index() function an error is generated but instead the find() function returns -1.
Example: text.find("s") # -1
text.index("s) # return error
Because small "s" is not found in the string "Data Science"
