如何在python中并排打印嵌套列表到宪章

Question

python中

a = [['z', 'G', 'j', 'E', 'U'], ['%', '#', '(', '!', ')'], ['6', '4', '8', '1', '3']]

我想把上面的嵌套列表打印成并排的字符示例输出:

zGjEU%#(!)64813

怎么做?

Answer 1

考虑一个嵌套式推导和str.join:

>>> a = [['z', 'G', 'j', 'E', 'U'], ['%', '#', '(', '!', ')'], ['6', '4', '8', '1', '3']]
>>> print(''.join(c for chars in a for c in chars))
zGjEU%#(!)64813

Answer 2

a = [['z', 'G', 'j', 'E', 'U'], ['%', '#', '(', '!', ')'], ['6', '4', '8', '1', '3']]
result = ""
for item in a:
for char in item:
result += char

结果:

'zGjEU%#(!)64813'
