当导入到另一个模块时，Python正在从该模块打印所有内容

我有两个文件

funcattrib.py

test\u import.py

funcattrib.py

import sys

def sum(a,b=5):
    "Adds two numbers"
    a = int(a)
    b = int(b)
    return a+b

sum.version = "1.0"
sum.author = "Prasad"
k = sum(1,2)
print(k)

print("Function attributes: - ")
print("Documentation string:",sum.__doc__)
print("Function name:",sum.__name__)
print("Default values:",sum.__defaults__)
print("Code object for the function is:",sum.__code__)
print("Dictionary of the function is:",sum.__dict__)

#writing the same information to a file

f = open('test.txt','w')
f.write(sum.__doc__)
f.close()
print("\n\nthe file is successfully written with the documentation string")

import sys
from funcattrib import sum

input("press <enter> to continue")

a = input("Enter a:")
b = input("Enter b:")
f = open('test.txt','a')
matter_tuple = "Entered numbers are",a,b
print(matter_tuple)
print("Type of matter:",type(matter_tuple))
matter_list = list(matter_tuple)
print(list(matter_list))
finalmatter = " ".join(matter_list)
print(finalmatter)
f.write(finalmatter)
f.close()
print("\n\nwriting done successfully from test_import.py")

测试导入.py

import sys

def sum(a,b=5):
    "Adds two numbers"
    a = int(a)
    b = int(b)
    return a+b

sum.version = "1.0"
sum.author = "Prasad"
k = sum(1,2)
print(k)

print("Function attributes: - ")
print("Documentation string:",sum.__doc__)
print("Function name:",sum.__name__)
print("Default values:",sum.__defaults__)
print("Code object for the function is:",sum.__code__)
print("Dictionary of the function is:",sum.__dict__)

#writing the same information to a file

f = open('test.txt','w')
f.write(sum.__doc__)
f.close()
print("\n\nthe file is successfully written with the documentation string")

import sys
from funcattrib import sum

input("press <enter> to continue")

a = input("Enter a:")
b = input("Enter b:")
f = open('test.txt','a')
matter_tuple = "Entered numbers are",a,b
print(matter_tuple)
print("Type of matter:",type(matter_tuple))
matter_list = list(matter_tuple)
print(list(matter_list))
finalmatter = " ".join(matter_list)
print(finalmatter)
f.write(finalmatter)
f.close()
print("\n\nwriting done successfully from test_import.py")

导入系统 从funcattrib导入和 输入（“按继续”） a=输入（“输入a:”） b=输入（“输入b:”） f=打开（'test.txt'，'a'） matter\u tuple=“输入的数字是”，a、b 打印（物质组） 打印（“物质类型：，类型（物质组）） 物质列表=列表（物质元组） 打印（列表（事项列表）） finalmatter=“”.加入（事项列表） 打印（最终材料） f、 写入（最终材料） f、 关闭（） 打印（“\n\n从test\u import.py成功完成写入”） 我从

funcattrib.py

导入了

sum

函数。当我尝试执行test_import.py时，我看到了整个

funcattrib.py

的输出。我只想使用

sum

函数

请告知，我做错了什么，或者有没有其他方法可以在不实际执行模块的情况下导入模块？

导入模块“顶层”中的所有语句时都会执行

如果不希望发生这种情况，则需要区分作为脚本使用的模块和模块。使用以下测试进行测试：

if __name__ == '__main__':
    # put code here to be run when this file is executed as a script

将其应用于您的模块：

import sys

def sum(a,b=5):
    "Adds two numbers"
    a = int(a)
    b = int(b)
    return a+b

sum.version = "1.0"
sum.author = "Prasad"

if __name__ == '__main__':
    k = sum(1,2)
    print(k)

    print("Function attributes: - ")
    print("Documentation string:",sum.__doc__)
    print("Function name:",sum.__name__)
    print("Default values:",sum.__defaults__)
    print("Code object for the function is:",sum.__code__)
    print("Dictionary of the function is:",sum.__dict__)

    #writing the same information to a file

    f = open('test.txt','w')
    f.write(sum.__doc__)
    f.close()
    print("\n\nthe file is successfully written with the documentation string")

Python总是从上到下执行。函数定义和其他任何东西一样都是可执行代码。导入模块时，将运行该模块顶层的所有代码。Python必须全部运行，因为函数是代码的一部分

解决方案是保护您不希望在导入时在

下运行的代码，如果uuuu name\uuuuu==“\uuuuuuu main\uuuu”

块：

if __name__ == "__main__":
     print("Some info")
