so I have 2 dataframes df1 and df2. df1 names = ['Bob', 'Joe', '', 'Bob', '0000', 'Alice', 'Joe', 'Alice', 'Bob', ''] df1 = pd.DataFrame({'names': names,'ages': ages}) df2 names_in_student_db = [' Bob', ' Joe ', '', ' Bob ', 'Chris', 'Alice', 'Joe ', 'Alice ', ' Bob ', 'Daniel'] df2 = pd.DataFrame({'student_names': names_in_student_db,'grades': grades}) Now, I want to merge these 2 dataframes but obviously, there are 2 problems: names and names_in_student_db are not fully identical. Both of them contain duplicates — this seems to be making merge functions to throw an error. Also, duplicates in one column are not the same (meaning let's say, 1st Bob and 3rd Bob in any of these columns are not the same person), but let's say the 2nd Bob in 1st column and 2nd Bob in the 2nd column are

I am using the LightningJS framework for an app. In the docs it states: Lightning has many other tricks up his sleeve to save performance, such as not having to render invisible parts (alpha:0 or visible:false) and detecting when branches are guaranteed to be out of screen. However, when an element is not shown, the attribute visible is set to true , contrary to what I believed would happen. Am I misunderstanding the documentation, or am I missing something? If so, how can I detect when an element is off-screen so I can turn its visibility off? Via Active questions tagged javascript - Stack Overflow https://ift.tt/SXDj05R

Why is it bad practice to pass context directly into helper functions in python? Example: def api_build_payload(context=Context, field=str, new_value=Any): source https://stackoverflow.com/questions/71916022/bad-practice-to-pass-context-directly-into-helper-functions-in-python

I have defined a variable (a list) in a Python script A and import it in script B, like so: from app import keywords At some point script A updates the variable (appends list items), but while script B is running, the variable doesn't update. I've tried with reload but then I get following error message: TypeError: reload() argument must be a module Am I missing something? source https://stackoverflow.com/questions/71916018/updating-variable-imported-from-other-python-script

I am testing a simple nested for loop that combines year and month year_time = range(2014, 2016) month_time = [ '0101', '0201', '0301', '0401', '0501', '0601', '0701', '0801', '0901', '1001', '1101', '1201' ] for year_time in year_time: for month_time in month_time: print (str(year_time) + month_time) The ideal output is 20140101, 20140201 ... 20151101, 20151201 . However, the actual output is 20140101, 20140201 ... 20151 . Where do I get wrong? source https://stackoverflow.com/questions/71915722/nested-for-loop-is-incorrect-for-the-second-number
