Hi, in this project we use a series of left merges to create a big dataframe called ‘all_data’.
When I use the len() function in the first dataframe that I merge (the ‘left’ one) it gives me a different number of characters than in the big dataframe. The first one gives me 2000 and the final big one gives me 2594. Shouldn´t it give me the same number?
Thanks and happy coding!
