如何使用 python 從 dataframe 中的整行中提取數字元素

Question

Ex - 從第一行中提取所有數字

Answer 1

你能給出數據幀的csv文件以及你想提取哪些數字嗎？

這是類似數據框的一種方法

 #code to extract no. from a dataframe
from numpy.core.arrayprint import printoptions
import pandas as pd
import numpy as np

dict={'0':['almarai investors  according to investor type loss','almarai investors  according to investor type loss',
'savola group','hh prince','governmenatla','other'],
'1':['31 dec2020','percent','34.5%','23.7%','56.5%','9.1%'],'2':[np.nan,np.nan,1,1,5,4125],
'font':['Normal','Normal','Normal','Normal','Normal','Normal']}

df= pd.DataFrame(dict)
 

df_numerics=df.select_dtypes(include=np.number)
print(df_numerics)
