I am reading multiple JSON objects into one DataFrame. The problem is that some of the columns are lists. Also, the data is very big and because of that I cannot use the available solutions on the internet. They are very slow and memory-inefficient
I’m starting from the pandas DataFrame docs here: http://pandas.pydata.org/pandas-docs/stable/dsintro.html
What’s the Python way to read in a CSV file into a pandas DataFrame (which I can then use for statistical operations, can have differently-typed columns, etc.)?
I have the following DataFrame:
I have a dataframe contains orders data, each order has multiple packages stored as comma separated string [package & package_code] columns
Most operations in pandas can be accomplished with operator chaining (groupby, aggregate, apply, etc), but the only way I’ve found to filter rows is via normal bracket indexing
I want to print the whole dataframe, but I don’t want to print the index
I am very new to Json files. If I have a json file with multiple json objects such as following:
Note: the method can only compare identically-labeled DataFrame objects,
this means DataFrames with identical row and column labels.
I’m confused about the rules Pandas uses when deciding that a selection from a dataframe is a copy of the original dataframe, or a view on the original.
