When I run below python script using Jenkins, it is throwing below error.

Jenkins Cannot run program "python" CreateProcess error=2, The system cannot find the file specified


Below is my code and it works when I execute it directly.

import _mssql,os,datetime
if (os.getenv('ColumnName').isspace() or not os.getenv('ColumnName')):
print("White space Entered")
else:
print(var)


I am running Python 3.5.

Thank you.

Tried python -v and getting same error
