类型错误：必须str的，而不是在泡诠释排序

Question

我有这样那样的错误在我的Python代码排序算法（冒泡排序）

Traceback (most recent call last): File "D:\CSC\PYTHON SAMPLE CODES\bubstepbystep.py", line 13, in nlist = nlist + i TypeError: must be str, not int

我无法弄清楚发生了什么里面

。请帮帮我。

import time 

nlist = input("Enter series of numbers: ") 
swap = len(nlist) 
qty = len(nlist) 
print("Original:", nlist) 


for x in range(qty - 1): 
    for i in range(swap - 1): #swap 
    if nlist [i] > nlist [i+1]: 
     temp = nlist [i] 
     nlist = nlist + i 
     nlist [i+1] = temp 

     print("\nSwapping Index:", i,"and", i+1, "\n\rNew list:", nlist) 
     time.sleep(3) 
    else: 
     print("\nSwapping Index:", i,"and", i+1) 
     time.sleep(3) 
     print("Nothing to swap, skipping . . .") 
     time.sleep(3) 

swap -= 1

你的问题是你的输入，我想：它映射到正确的整数，事情看起来好多了。此外，您的交换代码不正确：

import time 

nlist = list(map(int, input("Enter series of numbers: ").split())) 
nlist 
swap = len(nlist) 
qty = len(nlist) 
print("Original:", nlist) 

for x in range(qty - 1): 
    for i in range(swap - 1): #swap 
     if nlist [i] > nlist [i+1]: 
      temp = nlist [i] 
      print(temp) 
      nlist [i] = nlist [i+1] 
      nlist [i+1] = temp 

      print("\nSwapping Index:", i,"and", i+1, "\n\rNew list:", nlist) 
      time.sleep(3) 
     else: 
      print("\nSwapping Index:", i,"and", i+1) 
      time.sleep(3) 
      print("Nothing to swap, skipping . . .") 
      time.sleep(3) 

swap -= 1 

print("Final:", nlist)
