从两个列表开始，例如：lstOne = [ '1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
lstTwo = [ '1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
我想让用户输入他们想要提取多少项，占整个列表长度的百分比，以及从每个列表中随机提取的相同索引。比如说我想要50%的产量newLstOne = ['8', '1', '3', '7', '5']
newLstTwo = ['8', '1', '3', '7', '5']
我使用以下代码实现了这一点：from random import randrange
lstOne = [ '1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
lstTwo = [ '1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
LengthOfList = len(lstOne)
print LengthOfList
PercentageToUse = input("What Percentage Of Reads Do you want to extract? ")
RangeOfListIndices = []
HowManyIndicesToMake = (float(PercentageToUse)/100)*float(LengthOfList)
print HowManyIndicesToMake
for x in lstOne:
if len(RangeOfListIndices)==int(HowManyIndicesToMake):
break
else:
random_index = randrange(0,LengthOfList)
RangeOfListIndices.append(random_index)
print RangeOfListIndices
newlstOne = []
newlstTwo = []
for x in RangeOfListIndices:
newlstOne.append(lstOne[int(x)])
for x in RangeOfListIndices:
newlstTwo.append(lstTwo[int(x)])
print newlstOne
print newlstTwo
但我想知道是否有一种更有效的方法来实现这一点，在我的实际用例中，这是从145000个项目中进行的子抽样。此外，randrange在这个尺度上是否足够没有偏见？
