#1 Created at ... [Delete] [Delete and Lock User]

将 quadratic函数文件命名为1.py。在python解释器导入时提示错误

SyntaxError：invalid syntax

#2 Created at ... [Delete] [Delete and Lock User]

提示是语法问题，应该是你的内容的问题

#3 Created at ... [Delete] [Delete and Lock User]

忘了补充，在python解释器中，输入

from 1 import quadratic

#错误显示
 File "<stdin>",line1
  from 1 import quadratic

SyntaxError: invalid syntax

改为

from a import quadratic

就可以了，又额外试了下1a与a1。发现首字符为数字就不行，这种函数导入时对数字的限制是因为什么呢？

#4 Created at ... [Delete] [Delete and Lock User]

函数名、模块名都是变量名，必须符合变量命名规则

#5 Created at ... [Delete] [Delete and Lock User]

懂了，谢谢
