Centos7

If you got corupted/truncated/deleted file while updating/writing a bad commands, and as a result you cannot run service/app. You might be interested in this command to reinstall them:

rpm -Va --nodeps --nodigest --noscripts --nosignature --nofiledigest --nomode --nordev --nouser --nogroup --nomtime | grep '/lib64' | awk '/^S..../{system("rpm -qf "$2)}' | sort | uniq | xargs yum reinstall -y

1. rpm

• Verifying a package compare information about the installed files in the package with information about the files taken from the package metadata stored in the rpm database. Among other things, verifying compares the size, type, hash of each file.

2. grep

• Take only file located where you want to verify,

Python naming conventions

This document gives coding conventions example for the Python code. This style guide evolves over time as additional conventions are identified and past conventions are rendered obsolete by changes in the language itself.

1. General

• Avoid using names that are too general or too wordy. Strike a good balance between the two.
  • Bad: data_structure, my_list, info_map, dictionary_for_the_purpose_of_storing_data_representing_word_definitions
  • Good: user_profile, menu_options, word_definitions
• Never use the characters as single character variable names:
• “l“ : lowercase letter el
