Python副業(yè)200元-實現(xiàn)簡單的Excel統(tǒng)計函數(shù)
剛剛吃完午飯打開python學(xué)習(xí)群看到螞蟻老師發(fā)布了一個新的兼職單子,正好這幾天剛看完excel辦公自動化的課程,趕緊接了單檢測一下自己學(xué)的怎么樣。
需求分析
根據(jù)原始數(shù)據(jù),計算出累計和、回撤、連續(xù)正確、連續(xù)錯誤、連續(xù)正確值與連續(xù)錯誤值6項數(shù)據(jù),其中原始數(shù)據(jù)大于等于0認(rèn)定為正確,原始數(shù)據(jù)小于0為錯誤。明白了要求,那我們就開始擼代碼吧~
解決步驟
import pandas as pd
#創(chuàng)建一個計算數(shù)據(jù)的函數(shù)
def calculate(df):
pass
#讀取原始數(shù)據(jù),將索引列去除
df = pd.read_excel('需求0621.xlsx',index_col=0)
#調(diào)用計算數(shù)據(jù)的函數(shù)
calculate(df)
先把整體思路寫好,再去想辦法計算每項數(shù)據(jù)
#計算累計和
lst1 = []
sum = 0
for i in range(df.shape[0]):
if i == 0:
lst1.append(df['N'][i])
sum += df['N'][i]
else:
sum += df['N'][i]
lst1.append(sum)
df['累計和'] = lst1
#計算回撤
lst2 = []
max = 0
for i in range(df.shape[0]):
if i == 0:
lst2.append(0)
elif df['累計和'][i] > max:
max = df['累計和'][i]
lst2.append(0)
elif df['累計和'][i] < max:
lst2.append(df['累計和'][i]-max)
elif df['累計和'][i] == max:
lst2.append(0)
df['回撤'] = lst2
#計算連續(xù)正確的個數(shù)
lst3 = []
correct = 0
for i in range(df.shape[0]):
if df['N'][i] >= 0:
correct += 1
lst3.append(correct)
else:
lst3.append(0)
correct = 0
df['連續(xù)正確'] = lst3
#計算連續(xù)錯誤的個數(shù)
lst4 = []
mistake = 0
for i in range(df.shape[0]):
if df['N'][i] < 0:
mistake += 1
lst4.append(mistake)
else:
lst4.append(0)
mistake = 0
df['連續(xù)錯誤'] = lst4
#計算連續(xù)正確值
lst5 = []
for i in range(df.shape[0]):
lst5.append('')
right = 0
for i in range(df.shape[0]):
if df['連續(xù)正確'][i] != 0:
right += df['N'][i]
elif df['連續(xù)正確'][i] == 0 and right != 0:
lst5[i-1] = right
right = 0
df['連續(xù)正確值'] = lst5
#計算連續(xù)錯誤值
lst6 = []
for i in range(df.shape[0]):
lst6.append('')
wrong = 0
for i in range(df.shape[0]):
if df['連續(xù)錯誤'][i] != 0:
wrong += df['N'][i]
elif df['連續(xù)錯誤'][i] == 0 and wrong != 0:
lst6[i-1] = wrong
wrong = 0
df['連續(xù)錯誤值'] = lst6
最后將dataframe保存到excel
df.to_excel('完成計算.xlsx')
print('保持成功')
最終結(jié)果

技術(shù)總結(jié)
雖然已經(jīng)完成了客戶的要求計算出了所有的數(shù)據(jù),但在寫代碼過程中計算的步驟都是基于python基礎(chǔ)語法實現(xiàn)的,對于pandas的使用還要繼續(xù)看看螞蟻老師的課程,只有通過大量的練習(xí)才能夠熟練的掌握
最后感謝螞蟻老師的肯定,讓我在學(xué)習(xí)python的道路上又多了一份信心~
今晚來螞蟻老師抖音直播間,Python帶副業(yè)全套餐有優(yōu)惠!!!
