标题: [问题求助] Python二维数组如何转换类型 [打印本页]

作者: netdzb 时间: 2020-12-4 11:55 标题: Python二维数组如何转换类型

[['1', '255']][['256', '509'], ['510', '763'], ['764', '1017'], ['1018', '1271'], ['1272', '1526']]
如何转换成
===>
[[1, 255]][[256, 509], [510, 763], [764, 1017], [1018, 1271], [1272, 1526]]

下面的代码直接报错
data = [['1', '255']][['256', '509'], ['510', '763'], ['764', '1017'], ['1018', '1271'], ['1272', '1526']]
datadata = int(data)

data = [['1', '255']][['256', '509'], ['510', '763'], ['764', '1017'], ['1018', '1271'], ['1272', '1526']]
你发的这个语法不正确，并非二维数组

data = [['256', '509'], ['510', '763'], ['764', '1017'], ['1018', '1271'], ['1272', '1526']]
data = [[int(y) for y in x] for x in data]

回复 2# ivor

我的代码有点笔误，问题已经解决，谢谢！

>>> data = [['256', '509'], ['510', '763'], ['764', '1017'], ['1018', '1271'], ['1272', '1526']]
>>> data = eval(str(data).replace("'",'').replace('"',''))
>>> data
[[256, 509], [510, 763], [764, 1017], [1018, 1271], [1272, 1526]]

有点取巧
但不限维度
