print ('\n'.join([' '.join([i for i in range(1,j)]) for j in range(2,6)]))

错误

TypeError：序列项0：预期的str实例，找到int

我通过链接TypeError: sequence item 0: expected string,int found告诉string.join connects elements inside list of strings,not ints.

我已经更新了我的代码，例如print ('\n'.join([' '.join([str(i) for i in range(1,6)]))

我收到错误TypeError: 'str' object is not callable

以下代码运行正常

print ('\n'.join([' '.join(['i' for i in range(1,6)]))
