自學新手想請問一下大家用dataFrame轉成Series 在取平均要怎麼算
怎麼跑都不對Orz
====================================
import pandas as pd
data=pd.DataFrame({
"name":["Amy","Bob", "Charles"],
"salary":["30000","40000","50000"]
})
salaries=data["salary"]
print("薪水的平均值",salaries.mean())
============================================
這樣算出來是100001333350000.0

data.salary.squeeze().mean()

為什麼要用字串…

"salary":["30000","40000","50000"] "30000" 是文字"30000" 是 string, 30000 才是 integer 整數data type 不對 所以取平均會錯

我覺得你要先去搞懂資料型態耶
