本文主要是介绍始料未及的COVID-19、延期的考试、又可以瞎倒腾的喜悦，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Hmmm，真的本来下定决心不要东摸西摸专心功课，但是确实发生了本次人类历史上的大事件（当然可能在以后的日子里这个也就是洒洒水水平）导致了考试的延期，我又再一次的东张西望起来。
hmmm，好吧为了庆祝又可以自由活动，特此献上抄来的小程序一篇。以下可以用在ledge nano x上面查阅ETH。ledger的椭圆曲线弧度做了修改，更加细化了。
# List accounts from the Ledger Nano X
# Works in OS/X and Linux. May work in Windows with Cygwin.
#
# How to use:
# 1. Save into a file, e.g., ~/bin/getNanoAccounts
# 2. Set the executable bit - `chmod 700 ~/bin/getNanoAccounts`
# 3. Run the script - `~/bin/getNanoAccounts`
