二进制搜索程序TypeError:无法将“int”对象隐式转换为str

Question

我用Java用python编写了一个简单的二进制程序，现在我对python还不太熟悉（不仅仅是new，我还花了20天的时间来学习它）。你知道吗

我得到这个错误：

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!")

当我试图在我的all程序中转换成整数时，我还是得到了同样的错误。你知道吗

我们将不胜感激！！！

    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")
