Python之删除现在小于其后面数字的所有数字

我在我的函数文件中为此创建了一个函数:

def removeNum(myList): 
    listSize = len(myList) -1 
    loop = 0 
    while loop < listSize: 
        if myList[loop] > myList[loop + 1]: 
            myList.remove(myList[loop + 1]) 
            listSize = listSize - 1 
        loop = loop + 1 
 
    return myList 

我的主程序看起来像:(我使用 removeNum 函数，我在代码底部遇到了问题。)

import functionsFile 
 
 
 
 
finalDataList = [] 
openFinalData = open("FinalData.data") 
for entry in openFinalData: 
    entry = entry.strip() 
    entry = int(entry) 
    finalDataList.append(entry) 
 
 
print("The file has been read") 
 
listSum = 0 
for numb in finalDataList: 
    listSum = listSum + numb 
 
listAvg = listSum / len(finalDataList) 
listAvg = round(listAvg,2) 
 
print("The sum of all the numbers:--> "+str(listSum)) 
 
print("The average of the numbers is:--> "+str(listAvg)) 
 
 
 
functionsFile.firstTen(finalDataList) 
functionsFile.lastTen(finalDataList) 
 
finalDataList.sort() 
finalDataList.reverse() 
 
print("After sorting the numbers") 
 
functionsFile.firstTen(finalDataList) 
functionsFile.lastTen(finalDataList) 
 
oddNumList = [] 
for numb in finalDataList: 
    oddNumList.append(functionsFile.makeOdd(numb)) 
 
finalDataList = oddNumList 
 
newListSum = 0 
for numb in finalDataList: 
    newListSum = newListSum + numb 
 
newListAvg = newListSum / len(finalDataList) 
newlistAvg = round(newListAvg,2) 
 
 
print("After replacing the list with all the answers," 
      +"here are the new totals") 
 
 
print(" The new sum of all the numbers will be: "+str(newListSum)) 
 
print("The new average of all the numbers will be:"+str(newListAvg)) 
 
print(" ") 
 
functionsFile.firstTen(finalDataList) 
functionsFile.lastTen(finalDataList) 
 
print(" ") 
print(" ") 
 
 
functionsFile.removeNum(finalDataList) 
 
 
print(finalDataList) 
 
openFinalData.close() 

当我运行程序时，它没有打印出从上面的 removeNum 函数修改后的新列表，是我的函数有问题还是我的主程序有问题？我没有收到任何错误。任何想法将不胜感激。谢谢。

请您参考如下方法:

解决该问题的一种方法是zip 将列表自身的副本偏移 1，然后使用列表推导式进行过滤，如下所示:

ls = [1, 3, 0, 7, 9, 4] 
zipped = zip(ls, ls[0:1] + ls[:-1]) 
ls_filtered = [p[0] for p in zipped if p[0] >= p[1]] 
# ls_filtered is now [1, 3, 7, 9]
