# Init System Path wrapper and read its actual value
syspath_wrapper = winsyspath.WinSysPath()

# Try to add a path into System path
try:
    if syspath_wrapper.add(path):
        print("The path "{}" is correctly added to the System Path".format(path))
    else:
        print("The path "{}" is already in System Path, so cannot be added".format(path))
except (EnvironmentError, WindowsError, OSError, ValueError) as ex:
    print("Error -> {}".format(str(ex)))

# Reload System path value (needed only if it is modified outside python)
syspath_wrapper.reload()

# Print System Path value as a list
print(syspath_wrapper.get())

# Print System Path value as a string
print(syspath_wrapper.get_str())

# Try to remove a path from System path
try:
    if syspath_wrapper.remove(path):
        print("The path "{}" is correctly removed from System Path".format(path))
    else:
        print("The path "{}" is not in System Path, so cannot be removed".format(path))
except (EnvironmentError, WindowsError, OSError, ValueError) as ex:
    print("Error -> {}".format(str(ex)))
