我有一个元组列表，如何取出特定元素？

Question

I have a list of tuples like:

>>>list
[('the', 248),
 ('I', 81),
 ...
 ('I', 81)]

I want to take out a specific element like ('to',248), how should I index the element and get it?

Answer 1

>>> l =[('the', 248), ('I', 81), ('I', 81)]
>>> x = [i[1] for i in l]
>>> x
[248, 81, 81]

Answer 2

I'm not sure what you exactly mean by this question, but if you want to take an element out with specific qualities, you would just use index() (no matter the data type):

# x = [("string0",0),("string1",1),("string2",2),("string3",3)]
# Example outputs:
>>> x.index(("string0",0))
0
>>> x.index(("string2",2))
