创建长度不等的两个向量之间存在差异的pandas数据帧

import pandas as pd

vector1 = [1, 2, 3, 4, 5]
vector2 = [1, 2, 4]

series1 = pd.Series(vector1)
series2 = pd.Series(vector2)

df = pd.DataFrame()

df['Vector1'] = series1
df['Vector2'] = series2

df = df.fillna(0)

df['Difference'] = df['Vector1'] - df['Vector2']

import pandas as pd

vector1 = [1, 2, 3, 4, 5]
vector2 = [1, 2, 4]

series1 = pd.Series(vector1)
series2 = pd.Series(vector2)

df = pd.DataFrame()
df['Vector1'] = series1
df['Vector2'] = series2

df = df.fillna(0)
df['Difference'] = df['Vector1'] - df['Vector2']

print(df)
