This Python Array tutorial explains what is an Array in Python, its syntax, how to perform various operations like sort, traverse, delete etc
Since array indexes begin at 0, the statement inside the loop adds 1 to the value of the i counter to calculate the current index. 1: 2 2: 4 3: 6 4: 8 The output returns the index number of the current element in the array along with the value itself. The index and the value ...
