How to move all zeros in int array to the end with Python

Answer 1

def move_zeros_to_end(arr): 
    j = 0
    ln = len(arr)
    
    for i in range(ln): 
        if arr[i] != 0: 
            arr[j] = arr[i] 
            j+=1
      
    while j < ln: 
        arr[j] = 0
        j += 1
        

        
arr = [0, 3, 4, 0, 6, 0, 0, 8, 9, 0] 
move_zeros_to_end(arr) 
print(arr) 


'''
run:

[3, 4, 6, 8, 9, 0, 0, 0, 0, 0]
