EnvironmentError Exception in Python
EnvironmentError is the base class for errors that come from outside of Python (the operating system, file system, etc.). It is the parent class for IOError and OSError exceptions.
- exception IOError – It is raised when an I/O operation (when a method of a file object ) fails. e.g “File not found” or “Disk Full”.
- exception OSError – It is raised when a function returns a system-related error.
Any example of an IOError or OSError should also be an example of Environment Error.
Example 1 :
Python3
import sys
try :
file = open ( "GeeksforGeeks.txt" , 'r' )
except Exception as e:
print (e)
print (sys.exc_info()[ 0 ])
|
Output
[Errno 2] No such file or directory: 'GeeksforGeeks.txt'
<class 'FileNotFoundError'>
Example 2 :
Python3
import os
import sys
try :
for i in range ( 7 ):
print (i)
print (os.ttyname(i))
except Exception as e:
print (e)
print (sys.exc_info()[ 0 ])
|
Output
0
[Errno 25] Inappropriate ioctl for device
<class 'OSError'>
Example 3 :
Python3
import sys
import os
try :
os.rmdir( 'GEEKS' )
except Exception as e:
print (e)
print (sys.exc_info()[ 0 ])
|
Output
[Errno 2] No such file or directory: 'GEEKS'
<class 'FileNotFoundError'>
