METHOD 1
当在 IPython 中运行时,有一个名为的全局变量集__IPYTHON__
。您可以通过以下方式检查是否存在:
try:
__IPYTHON__
except NameError:
print "Not in IPython"
else:
print "In IPython"
METHOD 2
As this thread指出您还可以寻找get_ipython
脚本中的函数不仅可以检查您是否从 IPython 运行,还可以检查 IPython 的配置。
METHOD 3
您还可以使用inspect模块来检查堆栈并查明您是否正在从交互式解释器等运行。
所以一个示例文件:
# test.py
import inspect
for frame in inspect.stack():
print frame
当从命令行运行时python test.py
输出是:
(<frame object at 0x100378530>, 'test.py', 3, '<module>', ['for frame in inspect.stack():\n'], 0)
When execfile
来自交互式解释器的:
>>> execfile( "test.py" )
(<frame object at 0x1003795e0>, 'test.py', 3, '<module>', ['for frame in inspect.stack():\n'], 0)
(<frame object at 0x100379430>, '<stdin>', 1, '<module>', None, None)
在 IPython 中运行时:
In [1]: %run test
