Turns out that having duplicate entries in the index of one of the DataFrames was the culprit. #pandas #pythonprogramming #python #beginnerpython #datascience

Today I stumbled upon this "Reindexing only valid with uniquely valued Index objects" error, when trying to concatenate multiple dataframes that had a partially common index. Why does this occur? #python #pandas #beginnerpython #beginnerpandas #pythonprogramming #pythonlearning

What is the error in this block of code?!. HINT: #womenwhocode #wwcode #python #beginnerpython #variables #learnpython #beginnerpythonstudygroup #python101 #pythoncoding #pythoncode #pythonprogramming #wwcodepython

Comparing floats in #pytest can be done using #pytest.approx, with the abs argument set to the plus/minus tolerance that we want. #python #beginnerpython #pytest #datascience #tdd #pythonprogramming #pythonlearning #pythontests

This is a simple way to initialize a #DataFrame with some random #data and filter it by a condition.#python #beginnerpython #beginnerpandas #DataScience #learningpython

This is how you turn a DataFrame into a dictionary, when you want to group by a certain column. #pandas #Python #pythonlearning #beginnerpython #datascience #datasciencelearning

What is a possible reason why the resulting dataframe is empty in the following example?.#pandas #python #beginnerpython #datascience
