How to deal with an Item in a List in Python?
This recipe helps you deal with an Item in a List in Python
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]
