list(set(map(lambda tp_id : tp_id if not ('#' in tp_id) and len(tp_id.strip().replace('\n', '')) > 0else None, open('tp_list.txt').readlines()).sort())) 为了练习map,想着把一个循环写成一行代码. 结构跑程序时出了一个问题:TypeError: 'NoneType' object is not iterable. 找了半天错误(写成一行代码在这…

TypeError: 'int' object is not callable 这个错误的原因很简单 看下面的程序: def loss(a,b): return a-b loss = 0 loss = loss(5,2)+1 错误定位: loss = loss(5,2)+1TypeError: 'int' object is not callable 原因: 函数名loss 变量名loss 重合!!! 以此类推到其他类型的错误…
