Binary Search Program - TypeError: Can't convert 'int' object to str implicitly

Question

我从 Java 开始在 python 中制作了一个简单的二进制程序，目前我是 Python 的新手（不仅仅是 new 但我花了 20 天的时间来学习它）。

我收到这个错误：

Enter the number of Element: 
5
Traceback (most recent call last):
  File "C:\Users\raj\Documents\EclipseProject\PythonProject1\myProgram.py", line 15, in <module>
    print("Enter "+int(n)+" Elements")
TypeError: Can't convert 'int' object to str implicitly

这是我的程序：

array = []

print("Enter the number of Element: ")
n = input()
n = int(n)

array = [n]

print("Enter "+int(n)+" Elements")

for i in (0, n):
    array[i] += input()

print("Enter the element, you want to find:")
search = input()
search = int(search)

first = 0
first = int(first)

last = n-1
last = int(last)

middle = (first+last) / 2
middle = int(middle)

while(first <= last):
    if array(middle) < search:
        first = middle + 1
        first = int(first)

    elif array[middle] == search:
        print(int(search)+" Value found at location "+int((middle+1)))
        break

    else:
        last = middle - 1
        last = int(last)
        middle = (first+last)/2
        middle = int(middle)

if first>last:
    print(int(search)+" is NOT present in the list!")

当我在我的所有程序中尝试转换为整数时，但我仍然遇到同样的错误。

不胜感激！！！

    print("Enter "+int(n)+" Elements")
TypeError: Can't convert 'int' object to str implicitly

你看到错误了吗？试试这个：

    print("Enter "+str(n)+" Elements")
