Python Pandas学习之series的二元运算详解_python

# importing pandas module  
import pandas as pd  
 
# 创建一个 series
data = pd.Series([5, 2, 3,7], index=['a', 'b', 'c', 'd'])
 
# 创建一个 series
data1 = pd.Series([1, 6, 4, 9], index=['a', 'b', 'd', 'e'])
 
print(data, "\n\n", data1)

# 使用 .add 添加两个 series
data.add(data1, fill_value=0)

# importing pandas module  
import pandas as pd  
 
# 创建一个 series
data = pd.Series([5, 2, 3,7], index=['a', 'b', 'c', 'd'])
 
# 创建一个 series
data1 = pd.Series([1, 6, 4, 9], index=['a', 'b', 'd', 'e'])
 
print(data, "\n\n", data1)

# 使用 .sub 减去两个 series
data.sub(data1, fill_value=0)
