Answer 1

您需要使用类似：

print('[{0}]'.format(','.join(map(str, l))))

Answer 2

如果结果太大，可以修改：

print(repr(l).replace(' ', ''))

Answer 3

加入列表元素。

print("[" + ",".join([str(i) for i in l]) + "]")

Answer 4

You could convert it to a string and then replace the spaces. Eg:

print ("{}".format(l)).replace(' ', '')
