Linu下獲取python的版本號

1 在linux命令行底下經過python -V查看python版本號

suiyc@suiyc-A76GMV:~/sycworkspace/simple-sample$ python -V 2>&1 | awk '{print $2}'

輸出結果示例：2.7.3

2 直接在命令行中輸入python

示例： suiyc@suiyc-A76GMV:~/sycworkspace/simple-sample$ python Python 2.7.3 (default, Feb 27 2014, 19:58:35) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information.

3 經過python的platform模版獲取版本號

suiyc@suiyc-A76GMV:~/sycworkspace/simple-sample$ python -c 'import platform; print platform.python_version()' 2.7.3

4 經過python的sys模塊獲取版本號

suiyc@suiyc-A76GMV:~/sycworkspace/simple-sample$ python -c 'import sys; print sys.version' 2>&1 2.7.3 (default, Feb 27 2014, 19:58:35) [GCC 4.6.3]

能夠經過提取相應字段獲取版本號 suiyc@suiyc-A76GMV:~/sycworkspace/simple-sample$ python -c 'import sys; print sys.version' 2>&1 | awk '$1~/[0-9].[0-9].*/{print $1}' 2.7.3
