Python determine whether a file exists, and delete files api (which determine files not think this can make compatible jenkins strong working directory that problem)

In the absence of judgment file api:

os i.e. operating system (OS), Python os module encapsulates the common file and directory operations.

os.path module is used to obtain the attributes of the file, exists is "present" means, so that the name implies, os.path.exists () is to determine whether the file exists in parentheses mean, can be a file path within the parentheses.

For chestnut:

User.py a file to exist in the current directory

Enter the code: 

OS Import
path os.path.exists = ( 'user.py')
Print (path)
output: 

True

Process Finished with Exit code 0
if not, return is FALSE.

Delete files api:

if os.path.exists(dest_file):
　　os.remove(dest_file)
