Is there a way to force merge two excel tables with no common column? Using Python

Question

I have two excel files that I want to join their tables together but the problem is there isn’t a common column to join them with.

For example generalized to get to the point:

file 1

customer_id
1
2

file 2

purchase_id	purchase_amount
501	five
502	two

I want it to look like this

customer_id	purchase_id	purchase_amount
1	501	five
2	502	two

so far I have tried this but with no avail.

import pandas 

f1= pandas.read_excel(file1.xlsx)
f2= pandas.read_excel(file2.xlsx)

#merge file
f3=f1[["customer_id"]].merge(f2[["purchase_id", "purchase_amount"]])

You are looking for pd.concat:

import pandas as pd  # alias pandas

df1 = pd.read_excel('file1.xlsx')
df2 = pd.read_excel('file2.xlsx')

out = pd.concat([df1, df2], axis=1)
print(out)

# Output
   customer_id  purchase_id purchase_amount
0            1          501            five
1            2          502             two
