我试图通过使用基于索引的行位置简单地获得df的子集。但是,出于某些原因,以下代码有时返回空数据帧:
idx1 = 12105 # Get first index of interest
idxn = 12120 # Get last index of interest
print('idx1:',idx1)
print('idxn:',idxn)
rep = dist.iloc[idx1:idxn] # Get data between indexes of interest
print(rep)
“dist”数据帧(“Frame”是索引):
dist =
Frame dist
12094 8.523
12095 9.776
12096 11.028
12097 12.105
12098 13.239
12099 14.354
12100 15.510
12101 16.620
12102 17.690
12103 18.777
12104 19.838
12105 20.795
12106 21.783
12107 22.878
12108 23.782
12109 24.686
12110 25.595
12111 26.485
12112 27.254
12113 28.067
12114 28.816
12115 29.558
12116 30.316
12117 30.925
12118 31.497
12119 32.100
12120 32.791
12121 33.308
12122 33.841
12123 34.440
输出:
idx1: 12105
idxn: 12120
Empty DataFrame
Columns: [dist]
Index: []
我一辈子都不明白为什么会发生这种事
