在python中打印一个二维数组（m * n）

Question

import numpy as np

a = (['a','b','c',],['d','e','f','g'],['h','i','j','k'])

for row in a:
    print row

for i in range(0,4):
    for j in range(0,4):
        print a[i][j]

我想在n!=m打印一个数组。我上面的代码我收到以下错误。

Traceback (most recent call last):
  File "/Users/pankajsehgal/mystuff/Python_Practise/2darray", line 10, in <module>
    print a[i][j]
IndexError: list index out of range

我知道它超出范围，有没有办法打印它。没有使用numpy。

Answer 1

intValue

或者只是：

import numpy as np

a = (['a','b','c',],['d','e','f','g'],['h','i','j','k'])

for row in a:
    print row

for i in range(len(a)):
    sublistlen = len(a[i])
    for j in range(0,sublistlen):
        print a[i][j]
