For data processing in Python, Pandas and NumPy are super useful.
Before installing Pandas and NumPy, you should have pip on your Centos 7.
Installing Pandas by pip on Centos 7
If you have pip installed on your Centos 7, you can simply install Pandas like below:
# pip install pandas
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Installing NumPy by pip on Centos 7
# pip install numpy DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support Requirement already satisfied: numpy in /usr/lib64/python2.7/site-packages (1.16.5)
In my case, NumPy is already installed, so the above message appeared.
