將數組的集合傳遞給函數參數

Question

如何創建數組並將其傳遞給函數，讓函數對集合中的每個數組執行操作並將數組（可能以集合形式）返回給常規？數組需要保持自己的身份（通過引用傳入和傳出操作函數）。這將幫助我清理並壓縮當前的代碼。我不是一個專業的程序員，所以我意識到我的代碼可以大大改善。任何指導表示讚賞。

的當前的代碼示例：

import numpy as np 

# Function that performs some operation on array (matrix) 
def addLine(x): 
    x = np.vstack([x,np.random.rand(1,5)]) 
    return x 

def mainLoop(): 
    A = np.zeros((1,5),dtype=np.float32) 
    B = np.ones((1,5),dtype=np.float32) 
    C = np.ones((1,5),dtype=np.float32) 

    # Do stuff 

    A = addLine(A) 
    B = addLine(B) 
    C = addLine(C) 

我想這樣做：

# Function that accepts a collection of arrays as argument, performs 
# operation, and returns modified arrays to the same identity/name  
def addLines(x): 
    for n in range(len(x)): 
     x[n] = addLine(x) 
     return x[n] 

def mainLoop(): 
    A = np.zeros((1,5),dtype=np.float32) 
    B = np.ones((1,5),dtype=np.float32) 
    C = np.ones((1,5),dtype=np.float32) 

    # Do stuff 
    # Create a collection of all arrays to perform operations on 
    AllArrays = [A,B,C] 

    # Pass collection of arrays to function (I likely need a for loop here) 
    AllArrays = addLines(AllArrays) 

    # Perform further operations on individual arrays 
    A = A+2 
    B = B+1 
    C = C-1 

Answer 1

這個怎麼樣細微的變化？

def addLine(*args): 
    args = map(lambda x: np.vstack([x,np.random.rand(1,5)]), *args) 
    return args 

AllArrays = addLine(AllArrays) 

A, B, C = AllArrays 

A 

array([[ 0.  , 0.  , 0.  , 0.  , 0.  ], 
     [ 0.66237197, 0.07125813, 0.5454597 , 0.44901189, 0.89820099]])
