這樣做我可以找到具有相等 p["Sent"].values 的應用程序名稱：
df=p.loc[p["Sent"]==n["Sent"]]
print(df)
Output:
ValueError: Can only compare identically-labeled Series objects
您正在比較具有不同行的數據幀。
我會這樣做。 考慮這種情況。
name p n
app1 5 5
app2 8 6
app3 7 7
app4 10 8
app5 3 NaN
此代碼打印 app 和 num 的名稱，其中“p”和“n”數字相同。
# make dataframe p, n
p = pd.DataFrame([5, 8, 7, 10 ,3], index=['app1', 'app2', 'app3', 'app4', 'app5'], columns=['p'])
n = pd.DataFrame([5, 6, 7, 8, None], index=['app1', 'app2', 'app3', 'app4', 'app5'], columns=['n'])
# combine p and n with concat
df = pd.concat([p, n], axis=1)
# check equality
for i in range(len(df)):
if df.iloc[i]['p'] == df.iloc[i]['n']:
print(df.index[i], df.iloc[i]['p'])
# Outputs are
# app1 5.0
# app3 7.0
