Python:将整数列表为单个数字吗? [英] Python: List to ints to a single number?

问题描述

如果是整数，我有几个清单:

Say i have a several list if ints:

x =  [['48', '5', '0'], ['77', '56', '0'],
['23', '76', '34', '0']]

我希望将此列表转换为单个数字，但是单个数字类型仍然是整数，即:

I want this list to be converted to a single number, but the the single number type is still an integer i.e.:

4850775602376340

我一直在使用以下代码来执行该过程:

i have been using this code to carry out the process:

num = int(''.join(map(str,x)))

但我不断收到值错误.

如果我的列表中包含负整数，我该如何将其转换为绝对值?然后将它们转换为一个数字?

Also if my list contained negative integers how would i convert them to there absolute value? Then convert them to a single number?

x2 = [['48'，'-5'，'0']，['77'，'56'， '0']， ['23'，'76'，'-34'，'0']]

x2 = [['48', '-5', '0'], ['77', '56', '0'], ['23', '76', '-34', '0']]

x2 = 4850775602376340

x2 = 4850775602376340

提前谢谢.

推荐答案

它是列表的列表，所以

num = int(''.join(''.join(l) for l in lists))

或

def flatten( nested ):
    for inner in nested:
        for x in inner:
            yield x

num = ''.join(flatten(lists))
