How to Iterate Over Indexes in Python
Keep in mind that the range() function needs at least one argument. Since indexing in Python begins at 0, you can use the length of the sequence as the sole argument for the range() function.
To determine the length of a sequence, employ the len() function. For example, you can loop through the list from earlier sections, but this time by its indices.
12345678# Initial list values = [1, [2, 3], 4, "code"] # Initialize a for loop over indexes for i in range(len(values)): print("Index:", i) print("Value:", values[i]) print("----") # Delimiter
At each iteration of the loop, the variable i sequentially traverses the indices of values, ranging from 0 to 3.
