I have two csvs
I am trying to join the two dataframes where the Stocknumber matches, but it is only returning 77 results except the expected 140
here is my code
import pandas as pd
df=pd.read_csv('C:/Users/Starshine/Desktop/vdp.csv')
df = df.iloc[: , :-1]
df['StockNumber']=df['URL'].str[-8:]
df['StockNumber']=df['StockNumber'].str.strip('/')
df['StockNumber']=df['StockNumber'].str.strip('-')
df.to_csv('C:/Users/Starshine/Desktop/panda.csv',index=False)
dfs=pd.read_csv('C:/Users/Starshine/Desktop/a2.csv')
dfs.rename(columns={'Stock #': 'StockNumber'}, inplace=True)
dfs = dfs.iloc[: , :-2]
dfs['Stock']=df['StockNumber']
sf=pd.merge(dfs,df,on='StockNumber')
sf.to_csv('C:/Users/Starshine/Desktop/test21.csv',index=False)
print (sf)
What am I doing wrong here?
