函数range()从你指定的数字1开始,并在你指定的第二个数字5结束,因此我们的输出就不包含数字5. 下面是python关于range函数的帮助文档: class range(Sequence[int]) Return an object that produces a sequence of integers from start (inclusive) to stop (exclusive) by step. range(i, j) produces i, i+1...
range(start, stop, step) Explanation start: The first number in the sequence (inclusive). Defaults to 0 if not specified. stop: The first number isnot includedin the sequence (exclusive). Required forrange()to function. step: The increment between numbers in the sequence. ...
第二四分位数(Q2):也称中位数(Middle Quartile or Median),等于该样本中所有数值由小到大排列后第50%的数字。 第三四分位数(Q3):也称上四分位数(Upper Quartile),等于该样本中所有数值由小到大排列后第75%的数字。 Q3和Q1的差距称为四分位距(InterQuartile Range, IQR):IQR=Q3-Q1 ...
