Doing “Page Visists Funnel Project” I have met a strange thing: the length of left-merged DF is longer than initial DF.
mergedDF = pd.merge(visits, cart, how="left") print(len(mergedDF)) print(len(visits)
This code gives me the following answers:
How can it be that the number of rows in the merged DF (2052) is bigger than in the initial one (2000)?
Thank you in advance for your help
