Question

The function below takes two parameters: a string parameter: CSV_string and an integer index. This string parameter will hold a comma-separated collection of integers: '111,22,3333,4'. Complete the function to return the indexth value (counting from zero) from the comma-separated values as an integer. For example, your code should return 3333 (not '3333') if the example string is provided with an index value of 2. Hint: you should consider using the split() method and the int() function.

Answer 1

To return the integer at a given index from a comma-separated string, split the string into a list and then convert the desired element to an integer.

Step-by-step explanation:

To obtain the indexth value from a comma-separated string of integers, you can use the split() method to create a list of substrings, then use the int() function to convert the desired element to an integer. Here's an example of how you could write such a function:

def get_index_value(CSV_string, index):
# Split the string into a list using the comma as a separator
elements = CSV_string.split(",")
# Convert the string at the given index to an integer
return int(elements[index])
If you call this function with the example string '111,22,3333,4' and the index 2, it will return the integer 3333.
