如何连接或合并 4 个不同的数据框？

Question

Whenever I try to concat([]) more than 3 dataframes I get disorganized results or output.

IE: When i concat three or two dataframes I get complete data,but when I attempt to concat a 4th dataframe. It doesn't gives me all the columns and gives the results a lil disorganized.

results = pd.concat([d1, d2, d3], axis= 1, join = 'inner')

'Code above gives me complete data'

results = pd.concat([d1, d2, d3, d4], axis= 1, join = 'inner')

'Code above gives me incomplete data columns'

Help please!

Thanks

Answer 1

pd.concat should work for this. Can you please show the output

meanwhile try using the following:

merged_df = (df1.merge(df2).merge(df3).merge(df4))
