在linux命令行下运行python,可以直接输出hello world
- jackywgw@jackywgw-A8F:~/python_learning$ python
- Python 3.3.6 (default, Apr 17 2015, 00:20:01)
- [GCC 4.9.2] on linux
- Type "help", "copyright", "credits" or "license" for more information.
- >>> print('hello world')
- hello world
- >>>
如果将print ('hello world')写入first_helloworld.py中,通过python first_helloworld.py可以输出hello world.
如果想直接运行./first_helloworld.py,则先要chmod u+x first_helloworld,然后还要在first_helloworld.py最前面加入#!/usr/bin/python3
- #!/usr/bin/python3
- print('hello world')
#!/usr/bin/python3 这个为python的可执行路径,可以通过which python3/ which python来获取。
- jackywgw@jackywgw-A8F:~/python_learning$ which python3
- /usr/bin/python3
- jackywgw@jackywgw-A8F:~/python_learning$ which python
- /usr/bin/python
- jackywgw@jackywgw-A8F:~/python_learning$
这样就可以直接运行./first_helloworld.py输出hello world了。
