如何在Python中的函數定義內部定義布爾值？

Question

我該如何定義一個在函數範圍內聲明的布爾變量？

我已經定義在下面的函數變量pass = True，函數定義中的處於if語句設置它的值：

def test(array, n): # Define the function test with input parameters array and n 
    pass = True # Initialize variable pass to the boolean value True 
    for i in n: # For n number of times, perform the following operation using i as a counter 
     for j in range(i+1,n): # Increment from i+1 to n using j as a counter 
     if(array[i] == array[j]): # If the ith element in array equals the jth element, execute the following code 
               # If one element is equivalent to any subsequent 
               # elements of the array, set pass = true 
      pass = False # define pass as false 

return pass # return pass

除了一些壓痕問題，我認爲是由於SO張貼和不是由於真正的代碼被錯誤縮進，問題是pass是python中的保留字 - 它是空操作。如果你有一個合法的標識符替換它（例如，shouldPass），你應該罰款：

def test(array, n): # Define the function test with input parameters array and n 
    shouldPass = True # Initialize variable shouldPass to the boolean value True 
    for i in n: # For n number of times, perform the following operation using i as a counter 
     for j in range(i+1,n): # Increment from i+1 to n using j as a counter 
      if array[i] == array[j]: # If the ith element in array equals the jth element, execute the following code 
               # If one element is equivalent to any subsequent 
               # elements of the array, set shouldPass = true 
       shouldPass = False # define shouldPass as false 

    return shouldPass # return shouldPass
