Question

我开始学习python。我编写了以下模块文件以导入到python中，但IDLE中的输出没有显示任何内容。请帮忙

Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'appName' of bean class [java.util.Properties]: Bean property 'appName' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我用过

def main():
    print("This program illustrates a chaotic function")
    x=eval(input("enter a number between 0 and 1:"))
    for i in range(10):
        x=3.9*x*(1-x)
        print(x)

main()

命令导入模块，但它不显示任何输出。

Answer 1

------- chaos.py ----------

def main():
    print("This program illustrates a chaotic function")
    x=eval(input("enter a number between 0 and 1:"))
    for i in range(10):
        x=3.9*x*(1-x)
        print(x)

------- fileimport.py ---------

import chaos
chaos.main()

注意这两个文件都应位于同一目录

中

Parent Folder
          |
          |----chaos.py
          |----fileimport.py

Answer 2

Main.py

import chaos
print(chaos.hello())

chaos.py

def hello():
   return "hello"

将模块文件导入python
