According to the answer to question, I installed readline for python to resolve backspace issue. If I logged in CentOS 7 as a root, I can backspace without any problems;however, if I logged in as a user, I have to run pip install readline to resolve backspace problem. I do not know where to set the readline so I do not need to reinstall it every time when I log in as a user. In my computer, it does not define "PYTHONSTARTUP" which is mentioned in one of solutions in question.
Any further help and suggestion would be highly appreciated.

No. My case is different from the one you gave. I did test the solutions given in the website. – Leon WANG Jan 07 '18 at 10:53

NOTE: My system is CentOS 7. Intel Python was installed. If you use different Python, please see corresponding websites.
After studying online, I installed anaconda2, and set ~/.bashrc:
module load anaconda/anaconda2
next, set ~/.pystartup (refer link)
import atexit import os,sys import readline import rlcompleter readline.parse_and_bind("tab: complete")
historyPath = os.path.expanduser("~/.pyhistory")
def save_history(historyPath=historyPath): import readline readline.write_history_file(historyPath)
if os.path.exists(historyPath): readline.read_history_file(historyPath)
atexit.register(save_history) del os, atexit, readline, rlcompleter, save_history, historyPath
In addition, my system is CentOS 7. The cluster is using intel compiler and Intel Python. Thus, if you are using Intel Python, please install anaconda3(may 2);else, please refer link.
