浅谈pandas dataframe对除数是零的处理

data2['营业成本率'] = data2['营业成本本年累计']/data2['营业收入本年累计']*100
data2['营业成本率'].replace([np.inf, -np.inf, "", np.nan], 0, inplace=True)

 shouru = series['营业收入本年累计']

data2['营业成本率'] = 0
data2['营业成本率'] = data2.apply(get_benrate, axis=1)

data2['三项费用完成比例本月数'] = 0
data2.loc[data2['任务指标三项费用'] != 0,'三项费用完成比例本月数'] = data2['三项费用合计本月数']/data2['任务指标三项费用']*100
