python - Filter a list of tuples based on condition

Question

I have a list like this:

A=[(1,'A'),(2,'H'),(3,'K'),(4,'J')]

Each member of this list is like this: (number, string)

Now if I want to select the members if the number is bigger than 2 and write the string, what should I do?

For example: selecting the member with a number bigger than 2. the output should be: 'K','J'

Answer 1

Use a list comprehension:

[y for x,y in A if x>2]

Demo:

>>> A=[(1,'A'),(2,'H'),(3,'K'),(4,'J')]
>>> [y for x,y in A if x>2]
['K', 'J']
>>>
