creating multiple excel worksheets using data in a pandas dataframe
Just started using pandas and python.
Pandas get the most frequent values of a column
i have this dataframe:
Pandas DataFrames with NaNs equality comparison
In the context of unit testing some functions, I’m trying to establish the equality of 2 DataFrames using python pandas:
Seaborn: countplot() with frequencies
I have a Pandas DataFrame with a column called “AXLES”, which can take an integer value between 3-12. I am trying to use Seaborn’s countplot() option to achieve the following plot:
Pandas filter dataframe rows with a specific year
I have a dataframe df and it has a Date column. I want to create two new data frames. One which contains all of the rows from df where the year equals some_year and another data frame which contains all of the rows of df where the year does not equal some_year. I know you can do df.ix['2000-1-1' : '2001-1-1'] but in order to get all of the rows which are not in 2000 requires creating 2 extra data frames and then concatenating/joining them.
What techniques can be used to measure performance of pandas/numpy solutions
The timeit.Timer.repeat documentation includes a very important note:
pandas DataFrame output end of csv
I wonder how to add new DataFrame data onto the end of an existing csv file? The to_csv doesn’t mention such functionality.
Matplotlib – fixing x axis scale and autoscale y axis
I would like to plot only part of the array, fixing x part, but letting y part autoscale. I tried as shown below, but it does not work.
What are Python pandas equivalents for R functions like str(), summary(), and head()?
I’m only aware of the describe() function. Are there any other functions similar to str(), summary(), and head()?
