Python實現在Excel中繪制可視化大屏的方法詳解

# 讀取Excel文檔並且指定工作表的名稱
file_name = 'Bike_Sales_Playground.xlsx'
df = pd.read_excel(file_name,sheet_name='bike_buyers')

# 新建一張工作表
with pd.ExcelWriter(file_name,#文檔的名稱

df.to_excel(writer, sheet_name='Working_Sheet',index = False)# 設置Index為False

# 從新的工作表當中來讀取數據

# 去掉重復值
df.drop_duplicates(keep='first', inplace=True, ignore_index=False)
    
# 針對婚姻狀況這一列，“已婚”替換成“M”，“單身”替換成“S”
df['Marital Status'] = df['Marital Status'].replace('M','Married').replace('S','Single')
    
# 針對性別這一列，“男性”替換成“F”，而“女性”替換成“M”
df['Gender'] = df['Gender'].replace('F','Female').replace('M','Male')

# 查看表格的前5行
df.head()

# 年齡數值的處理
