1：統計list中相同的個數，並按大小排序。

original_list = ['a', 'b', 'b', 'a', 'd', 'd', 'b', 'z', 'c', 'b', 'r', 's', 'h', 'f', 'f', 's', 'b', 'b', 'y', 'b']
counter = {}
for i in original_list:
    if original_list.count(i) > 1:
        counter[i] = original_list.count(i)

# 按字典的值，進行從大到排序
counter_list = list(zip(counter.values(), counter.keys()))
counter1_list 
 
= sorted(counter_list, reverse=True)

# # 按字典的鍵，進行從大到排序
# counter1 = sorted(counter.items(), key=lambda x: x[0], reverse=True)

for counter1 in counter1_list:
    print(counter1)

2：讀取excel中某一個sheet中的每一行資料。

import xlrd
excel_path = r'********'
data = xlrd.open_workbook(excel_path).sheet_by_name("sheet1
 
")
n_rows = data.nrows  # 行數
for i in range(0, n_rows):
    # 每一行資料
    row_values = data.row_values(i)
    print(row_values)

3：儲存資料到excel。

import pandas as pd
dict_content_list = [{'a': '1', 'b': '2'}, {'a': '3', 'b': '4'}]
data = pd.DataFrame(dict_content_list)
data.to_excel('./***.xls', encoding='
 
utf8', index=False)
