使用操作从Python列表创建numpy数组

pandas 在这方面相当擅长:

import pandas as pd
                      # set up DataFrame
transformed_data = (pd.DataFrame(data)
                      # convert to numeric
                      .apply(pd.to_numeric, errors='coerce')
                      # replace null with 0
                      # trying to cast as integer if possible
                      .fillna(0, downcast='infer')
                      # convert to numpy array
                      .to_numpy()
                   )

输出:

array([[    1, 12345,     1,     0,     0],
       [    1, 34567,     1,     1,     0]])

如果您的元组很小且大小固定,则可以使用列表理解:

result = [(a, int(b), c, d, 0 if e is None else e) for a, b, c, d, e in data]

或者稍微短一点:

result = [(d[0], int(d[1]), *d[2:4], d[4] if d[4] else 0) for d in data]
