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
.
