Pull boot and recovery, It may take a few minutes, please wait....

I tried cheking pull_boot_recovery process and found tools/pull-boot_recovery is symlinked to -> tools/bootimgpack/pull_boot_recovery.py

itried exectuing this python script(pull_boot_recovery.py) with python2.7
and here is the output

innfinite4evr@innfinite4evr-A780LB:/media/innfinite4evr/AndroWorks_ext4/flyme/tools/bootimgpack$ python2.7 pull_boot_recovery.py
I/pull_boot_recovery: Begin pull boot and recovery, make sure your phone was connected and adb devices is fine!
I/pull_boot_recovery: It may take a few minutes, please wait....
I/adb: waiting for devices....

I/pull_boot_recovery: adb connect success.

After that i tried runnning the same script with python3
and here is th output
