將數據讀入Python中的冒泡排序算法

Question

我的代碼段：

# BubbleSort in Python 3

def bubblesort(mylist):
    for i in range (0, len(mylist) - 1): 
        for j in range (0 , len(mylist) - 1 - i):
            if mylist[j] > mylist[j+1]:
                mylist[j], mylist[j+1] = mylist[j+1], mylist[j]
    return mylist

thelist = ['4','5','4','3','7','6','9','0']
print(bubblesort(thelist))

文件numbers.txt包含數據：

2 5 32 6 4 7 9 8 6 34 1343 5 5343

我試圖從這些文本文件中將這些數字讀入變量thelist 。 我需要更改/編寫什么代碼才能實現此目的？

Answer 1

該代碼將從文件中讀取，然后進行排序，然后保存到文件中。 並打印排序列表

def bubblesort(mylist):
    for i in range (0, len(mylist) - 1): 
        for j in range (0 , len(mylist) - 1 - i):
            if mylist[j] > mylist[j+1]:
                mylist[j], mylist[j+1] = mylist[j+1], mylist[j]
    return mylist

def read():
    #read from file
    f = open("numbers.txt","r")
    data = f.read().split()# convert string to list by split
    f.close()
    # for each element in list convert to int
    for i in range(len(data)):
        data[i] = int(data[i])
    return data

def write(thelist):
    #create edit the text file
    file = open("numbers.txt", "wt")
    # for each element in list write i value and add space between new value
    for i in range(len(thelist)):
        file.write(str(thelist[i]) + " ")
    file.close()

thelist = read()
print(bubblesort(thelist))
write(thelist)
