In the above example, we initialized the variablecwith the value 1. We multiplied this with every element of the list and displayed its final value. Further reading: Python concatenate string and int Read more → += in Python Read more → ...
demoList[i]=demoList[i]*3#Scalar value print(demoList) In the above code snippet: Create a list variable “demoList”. Initialize a for loop and start it from 0 up to the length of the list by using the len() method. For every iteration, take the element at the “i” index and...
