Python Pandas

What it is …

• A kind of python packages to deal with data as table format
• This package is good for data analysis.
• Most for data scientists

Importing this package

• command import pandas as pd

DataFrame

• one of data type in python
• table format
• provides various statistical, visualization functions
• used to read and save data as files — support various file format (e.g. csv, xlsx …)

  pd.read_csv('./[file_name]', encoding = 'utf8')
  
  pd.to_csv('./[file_name]', encoding = 'utf8', index = False)

  If you are using Mac Book, you do not have to write ‘utf8’ to encode files.

• This is the same as of List type, Numpy.
• iloc and loc is added in data frame type.
• You can also find out the data type of vector-data is the series type when the code for columns or rows is written.
• You can also find the data based on the columns. (or one column)
