如何使用Python比较Excel中的相邻单元格？

Question

I have two columns and I am trying to return the total count of rows where both adjacent cells within the two columns are identical. I am trying to iterate through each row of two columns and compare each item in the first column with its adjacent item in the second column ie

A | B
1 | 1
2 | 3
4 | 4

returns 2 for there are 2 pairs that are identical.

My two columns are Q and R, so far:

import openpyxl

excel_document = openpyxl.load_workbook('example.xlsx')


sheet = excel_document.get_sheet_by_name('Page 1')
created_closed = sheet['Q2':'R1844']
count = 0

for cell in column:
    if Q[2] == R[2]: #something along the lines of this
          count += 1

Answer 1

import pandas as pd

df = pd.read_excel('example.xlsx')
df = df[df['A'] == df['B']]
print (df.shape[0])

Answer 2

The answer that comes to mind is:

count = created_closed[created_closed['Q']==created_closed['R']].shape[0]

No for loop required because pandas takes care of that.

Answer 3

A - Try using numpy and pandas .

1- Find all intersections: This will return an array with the elements that were common in both columns

from pandas import read_excel
import numpy as np

df = read_excel('excel_data.xlsx', names=['A','B'], header=None)
np.intersect1d(df['A'], df['B'])

2- now count the length of the array

B- read each column and save to, two separate dictionary with key being position and value being the value at that position . Compare the two dictionaries and keep track of matches.

something like this, I am traveling right now so I can no test.

count = 0
col1 = {1:'a', 2:'b', 3:'c'}
col2= {1:'g', 2:'b', 3:'v'}

for key in col1.keys():
    if col1[key] == col2[key]:
        count = count + 1
