Recipe Objective

Have you tried to change any item in a array or tired to manupulate it?

So this is the recipe on how we can deal with an Item in a List in Python.

Step 1 - Creating List

We have created a list named sales with different values Sales = [482, 93, 392, 920, 813, 199, 374, 237, 244]

Step 2 - Changing Values

Here we have defined a function to return the values after adding 100 to the previous value. After that we have mapped this updated feature and sales. def updated(x): return x + 100 print(list(map(updated, Sales))) Now we have defined a loop in which we will add 10 to each value of previous feature i.e updated. salesUpdated = [] for x in Sales: salesUpdated.append(x + 10) print(salesUpdated) Now we have defined a mapping function to add 100 in each value of items in sales and we are using lambda function for this. print(list(map((lambda x: x + 100), Sales))) So the output comes as

[582, 193, 492, 1020, 913, 299, 474, 337, 344]

[492, 103, 402, 930, 823, 209, 384, 247, 254]

[582, 193, 492, 1020, 913, 299, 474, 337, 344]
