Python - Store a value in an array inside one for loop

Question

I would like to store each value of price in an array, getting it from a dict. I am a fresh at python, I spent hours trying to figure this out...

for item in world_dict:
     if item[1] == 'House':
       price = float(item[2])
       print p

The output is like:
200.5
100.7
300.9
...
n+100

However, I want to store it on this format : [200.5, 100.7, 300.9, ..., n+100]

Solution

Define a list and append to it:

prices = []
for item in world_dict:
     if item[1] == 'House':
       price = float(item[2])
       prices.append(price)

print(price)

or, you can write it in a shorter way by using list comprehension:

prices = [float(item[2]) for item in world_dict if item[1] == 'House']
print(prices)

Hope that helps.
