答案 0 :(得分:0)
尝试使用:
import pandas as pd
s = pd.Series([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13, 14, 15, 16, 17, 18, 19, 20])
s1 = s[0:5]
s2 = s[5:10]
s3 = s[10:15]
s4 = s[15:]
答案 1 :(得分:0)
您可以使用numpy
的{{1}}
array_split()
s_split = np.array_split(s, 4)
通过[0 1
1 2
2 3
3 4

答案 2 :(得分:0)
使用 numpy.array_split (https://numpy.org/doc/stable/reference/generated/numpy.array_split.html)!
这会将一个数组拆分为多个子数组。
import numpy as np
import pandas as pd
s = pd.Series([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20])
result = np.array_split(s, 4)
result
Out[2]:
[0 1
1 2
2 3
3 4
4 5
dtype: int64, 5 6
6 7
7 8
8 9
9 10
dtype: int64, 10 11
11 12
12 13
13 14
14 15
dtype: int64, 15 16
16 17
17 18
18 19
19 20
dtype: int64]
通过遍历列表或通过索引访问它们
result[0]
Out[3]:
0 1
1 2
