Code #4: For pivoting it possible. Pandas DataFrame is a two-dimensional, size-mutable, heterogeneous tabular data structure that contains rows and columns. Drop columns from a DataFrame can be achieved in multiple ways. In addition we pass a list of column labels to the parameter columns . generate link and share the link here. This data should be stored in two separate tuples that are supplied to the zip() initializer. Convert list of tuples to MultiIndex. The Pandas DataFrame is a structure that contains two-dimensional data and its corresponding labels.DataFrames are widely used in data science, machine learning, scientific computing, and many other data-intensive fields.. DataFrames are similar to SQL tables or the spreadsheets that you work with in Excel or Calc. And tuple can be considered as an item. So we can use strings, numbers (int or float), or tuples as keys.
