Python| Pandas TimedeltaIndex.difference

Python是一种用于进行数据分析的出色语言,主要是因为以数据为中心的Python包的奇妙生态系统。 Pandas就是其中之一,它使导入和分析数据变得更加容易。
Pandas TimedeltaIndex.difference()函数返回一个新索引,其中包含索引中不在其他索引中的元素。这是两个 Index 对象的集合差。如果可以排序,则已排序。

示例 #1:使用 TimedeltaIndex.difference()函数查找两个 TimedeltaIndex 对象的集差。

Python3
# importing pandas as pd
import pandas as pd
 
# Create the first TimedeltaIndex object
tidx1 = pd.TimedeltaIndex(data =['06:05:01.000030', '+23:59:59.999999',
                                 '22 day 2 min 3us 10ns', '+23:29:59.999999',
                                                         '+12:19:59.999999'])
 
# Create the second TimedeltaIndex object
tidx2 = pd.TimedeltaIndex(data =['09:11:18.000030', '+23:59:59.999999',
                                 '9 day 18 min 3us ', '+23:29:59.999999',
                                                     '+12:19:59.999999'])
 
# Print the first and second TimedeltaIndex object
print(tidx1, "\n", tidx2)


Python3
# find the set difference
tidx1.difference(tidx2)


Python3
# importing pandas as pd
import pandas as pd
 
# Create the first TimedeltaIndex object
tidx1 = pd.TimedeltaIndex(start ='1 days 02:00:12.001124', periods = 5,
                                              freq ='D', name ='Koala')
 
# Create the second TimedeltaIndex object
tidx2 = pd.TimedeltaIndex(start ='3 days 02:00:12.001124', periods = 5,
                                              freq ='D', name ='Koala')
 
# Print the first and second TimedeltaIndex object
print(tidx1, "\n", tidx2)


Python3
# find the set difference
tidx1.difference(tidx2)


输出 :

现在我们将使用 TimedeltaIndex.difference()函数来查找设置的差异。

Python3

# find the set difference
tidx1.difference(tidx2)

输出 :

正如我们在输出中看到的,TimedeltaIndex.difference()函数返回了一个新对象,该对象仅包含 tidx1 独有的那些元素。示例 #2:使用 TimedeltaIndex.difference()函数查找两个 TimedeltaIndex 对象的集差。

Python3

# importing pandas as pd
import pandas as pd
 
# Create the first TimedeltaIndex object
tidx1 = pd.TimedeltaIndex(start ='1 days 02:00:12.001124', periods = 5,
                                              freq ='D', name ='Koala')
 
# Create the second TimedeltaIndex object
tidx2 = pd.TimedeltaIndex(start ='3 days 02:00:12.001124', periods = 5,
                                              freq ='D', name ='Koala')
 
# Print the first and second TimedeltaIndex object
print(tidx1, "\n", tidx2)

输出 :

现在我们将使用 TimedeltaIndex.difference()函数来查找设置的差异。

Python3

# find the set difference
tidx1.difference(tidx2)

输出 :

正如我们在输出中看到的,TimedeltaIndex.difference()函数返回了一个新对象,该对象仅包含 tidx1 独有的那些元素。
