Connect your USBasp to computer.
Use this command to check if the computer recognize it:
# dmesg
[ 4734.960248] usb 5-1: new low-speed USB device number 21 using uhci_hcd
[ 4735.128594] usb 5-1: New USB device found, idVendor=16c0, idProduct=05dc

Check device info:
# udevadm info -a -p $(udevadm info -q path -n /dev/bus/usb/[bus#]/[device#])
# udevadm info -a -p $(udevadm info -q path -n /dev/bus/usb/005/021)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Create file usbasp.rules in /etc/udev/rules.d with content:
SUBSYSTEM=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05dc", GROUP="adm", MODE="0666"
Resstart udev:
# sudo restart udev
Then just unplug and plug the USBasp device again.

The philosopher Wittgenstein didn’t like the set theory and complained mathematics is “ridden through and through with the pernicious idioms of set theory,” He dismissed the set theory as “utter nonsense”, as being “laughable” and “wrong”. His criticism appeared years after the death of the German mathematician Georg Cantor, the founder of the set theory.
In this chapter of our Python tutorial we will have a closer look at the various ways of creating nicer output in Python. We present all the different ways, but we recommend that you should use the format method of the string class, which you will find at end of the chapter. “string format” is by far the most flexible and Pythonic approach.
