Python Pandas - 返回与当前值相同的 IntervalArray，但左侧闭合

要返回与当前值相同的 IntervalArray，但左侧闭合，请使用 set_closed() 方法并指定值 left。

首先，导入所需的库 −

import pandas as pd

创建 IntervalArray −

index = pd.arrays.IntervalArray.from_breaks(range(5))

显示间隔 −

print("IntervalIndex...\n",index)

返回一个间隔数组，它与当前间隔数组相同，但闭合在指定侧，即此处的“left” −

print("\nResult...",index.set_closed('left'))

示例

代码如下 −

import pandas as pd

# Create IntervalArray
index = pd.arrays.IntervalArray.from_breaks(range(5))

# Display the interval
print("IntervalIndex...\n",index)

# Display the interval length
print("\nIntervalIndex length...\n",index.length)

# the left bound
print("\nThe left bound for the IntervalIndex...\n",index.left)

# the right bound
print("\nThe right bound for the IntervalIndex...\n",index.right)

# Return an IntervalArray identical to the current one but closed on specified
# side i.e. "left" here
print("\nResult...",index.set_closed('left'))

输出

这将产生以下输出 −

IntervalIndex...
<IntervalArray>
[(0, 1], (1, 2], (2, 3], (3, 4]]
Length: 4, dtype: interval[int64, right]

IntervalIndex length...
Int64Index([1, 1, 1, 1], dtype='int64')

The left bound for the IntervalIndex...
Int64Index([0, 1, 2, 3], dtype='int64')

The right bound for the IntervalIndex...
Int64Index([1, 2, 3, 4], dtype='int64')

Result... <IntervalArray>
[[0, 1), [1, 2), [2, 3), [3, 4)]
Length: 4, dtype: interval[int64, left]
