I have a dataframe like this with many more variants and values in each x and y list: x y variant *BCDS%q3rn [45, 59] [18, 14] F^W#Bfr18 [82, 76] [12, 3] How can I iterate through each variant (each row has a unique string) and plot the x and y values in a scatterplot? This ..

I’m just aiming to gain some advice on solving an impending problem. Specifically, to measure the synchronisation of specific points throughout a time series. To achieve this, I’m hoping to use the Kuramoto model listed in this equation. Where the output (r) of the oscillator, returns a value between 0 and 1. Using the df ..
I have a dataframe of names (df): df: Group Name 0 A jim 1 B bob 2 C joe 3 A jane 4 C doe And a schedule dataframe (df1): df1: Group Due_Date Assignment 0 A 1-19 17:00 Quiz #1 A 1 B 1-21 16:30 Quiz #1 A 2 C 1-21 16:30 Quiz #1 A ..
I have a function that has two arguments that are both lists as shown below def myfunc(arg1, arg2): return arg1*arg2 arg1 = [1,2,3,4] arg2 = [10,9,8] I want to return a list of each possible PERMUTATION of the two arguments So the result should be something like [10,9,8,20,18,16…….] I believe this isn’t possible with maps ..
let’s say I have a room and a dataframe(/timeseries) df, which has minutely timestamps in one column df[‘timestamp’] and entries and exits for each minute in the other two columns df[‘entries’] & df[‘exits’] (those may be 0). Now I want to create a fourth column, which tells me how much people there are inside the ..
I have dataframe that looks like this: State State_theft_sum Model_1 Model_year_1 Alabama 2154 Chevrolet Pickup (Full Size) 2005.0 Alaska 547 Chevrolet Pickup (Full Size) 2003.0 Arizona 5270 Honda Accord 1997.0 DF goes on and on, so changing values separately isn’t the way. I though i might be able to replace them using result of loop ..
I created code to drop some rows according to certain condition : df3 = df_clean[(df_clean[‘group’] == ‘treatment’) & (df_clean[‘landing_page’] != ‘new_page’)].index df2 = df_clean.drop(df3 , inplace=True) df2.head() but I got this error: AttributeError: ‘NoneType’ object has no attribute ‘head’ Source: Python..
I understand that .apply() is slow in pandas. However, I have a function that acts on indexes, which I cannot figure out how to vectorize. I want this function to act on two sets of parameters, 500,000 and 1,500 long, though, so I do need to figure out an optimization. As it stands it looks ..
I have a few dataframes that I am trying to transfer to excel. Using this method, I successfully did so… writer = ExcelWriter(f’DRAGON{date}.xlsx’) stats.to_excel(writer, f’ELO{date}’) pdf.to_excel(writer, f’Playoffs{date}’) sec.to_excel(writer, f’Second Round{date}’) cf.to_excel(writer, f’Conference Finals{date}’) cham.to_excel(writer, f’Finals{date}’) df.to_excel(writer, f’Stanley Cup Winner{date}’) writer.save() writer.close() This worked for a while, but for some reason it stopped working the other ..
I have a file (txt) containing fake data with the following 3 columns: user_13 visit_19 1330760979 user_14 visit_20 1330732782 user_14 visit_21 1330769600 user_14 visit_22 1330783341 user_14 visit_23 1330796012 user_14 visit_24 1330797842 Using Pandas, how can I find out from the time stamps on the third column, the amount of users who visited the page between ..
