Divide two columns in a dataframe
Question
I would like to divide the values of two columns in a df in python.
So far I have
df3['Result'] = df3[1_x]/df3[1_y]
The columns formed after an inner merge. I keep on getting the error SyntaxError: invalid decimal literal
Does anyone know how to fix this?

Missing single quotes for column names 1_x and 1_y :
df3['Result'] = df3['1_x'] / df3['1_y']
# ^ ^ ^ ^
Reproducible error:
>>> 1_x
File "<ipython-input-4828-dea8fc3e99c1>", line 1
1_x
^
SyntaxError: invalid decimal literal
