怎么把包含元组的列表变成一个列表

Question

[(a,),(b,)(c,)...]怎么分割变成[a,b,c....]

Answer 1

a = [(1, 2,), (2, 3,), (4, 5)]
s = [j for i in a for j in i]
print s
------
[1, 2, 2, 3, 4, 5]

Answer 2

楼上写的太精炼了，高。我来个容易理解，但有些啰嗦的。

tuple_list = [(1, 2,), (2, 3,), (4, 5)]

result = []
for tuple_item in tuple_list:
  for i in tuple_item:
    result.append(i)

print(result)

Answer 3

a = [(1, 2,), (2, 3,), (4, 5)]
s = reduce(lambda x,y:list(x)+list(y), a)
print(s)
