How to divide two column in a dataframe
提问by RHTM
So, in my dataframe I have 2 columns. And I'd like to divide these 2 columns (a & b), value by value, and show it.
所以,在我的数据框中,我有 2 列。我想将这 2 列 (a & b) 按值分开并显示出来。
import pandas as pd
csv1=pd.read_csv('autoColumn A | Column B |
12-------|--2-------|
14-------|--7-------|
16-------|--8-------|
20-------|--5-------|
Result
6
2

4
.csv')
csv2=pd.read_csv('autoIn [158]:
df['Result'] = df['Column A']/df['Column B']
df
Out[158]:
Column A Column B Result
0 12 2 6.0
1 14 7 2.0
2 16 8 2.0
3 20 5 4.0
.csv')
df1 = pd.DataFrame(csv1, columns = ['Column A','Column B'])
df2 = pd.DataFrame(csv2, columns = ['Column A','Column B'])
dfnew = pd.concat([df1, df2])
The columns:
