将元组转换为列表

Question

我正在尝试将此元组转换为列表，但是当我运行此代码时：

mytuple=('7578',), ('6052',), ('8976',), ('9946',)
List=[]
for i in mytuple:
    Start,Mid,End = map(str, mytuple.split("'"))
    List.append(Mid)
print(List)

我收到此错误：

AttributeError: 'tuple' object has no attribute 'split'

输出应为：

[7578, 6052, 8976, 9946]

Answer 1

这就是你要找的

mytuple = (('7578',), ('6052',), ('8976',), ('9946',))
result = [int(x) for x, in mytuple]
print(result)

Answer 2

如果我正确理解，这就是您想要的：

mytuple = ('7578',), ('6052',), ('8976',), ('9946',)
result = [e for e, in mytuple]
print(result)

输出量

['7578', '6052', '8976', '9946']

Answer 3

我会使用itertools.chain.from_iterable （它的冗长程度太高而不是太错误）：

from itertools import chain
result = [int(x) for x in chain.from_iterable(mytuple)]
# vs         ... for x, in mytuple]; the comma is easy to miss

两种极端之间的某个地方是

result = [int(x) for x in chain(*mytuple)]
