保存一个hello.py文件在F:/data/python目录下
hello.py
>>> def hello(x): print x
目录
导入
>>> import sys>>> sys.path.append('F:/data/python') #添加路径>>> import hello>>> hello.hello(5) #调用5
不改变sys.path导入自定义模块:
第一种方法:将hello2.py文件放在D:/Python27/lib/site-packages目录下
>>> import sys,pprint>>> pprint.pprint(sys.path) ['', 'D:\\Python27\\Lib\\idlelib', 'F:\\data\\s', 'D:\\Python27', 'C:\\Windows\\system32\\python27.zip', 'D:\\Python27\\DLLs', 'D:\\Python27\\lib', 'D:\\Python27\\lib\\plat-win', 'D:\\Python27\\lib\\lib-tk', 'D:\\Python27\\lib\\site-packages']>>> import hello2>>> hello2.hello() hello,world!
第二种方法:将F:/data/python路径添加到环境变量(在系统变量中,添加PYTHONPATH变量,再将路径添加到值中)
>>> import sys>>> import hello>>> hello.hello(1)1
