Python 程序：計算列表差異

寫一個 Python 程序來找出兩個列表的區別。在本例中，我們將列錶轉換為集合，找到集合差異，然後將其轉換回列表。

# Difference Between two Lists

list1 = [1, 2, 4, 6, 8, 9]
list2 = [1, 3, 5, 7, 11, 9]

print("First  List Items = ", list1)
print("Second List Items = ", list2)

diff1 = list(set(list1) - set(list2))
diff2 = list(set(list2) - set(list1))

actualdiff = diff1 + diff2
print("List Difference Result = ", actualdiff)

尋找列表差異的 Python 程序

這個 Python 程序允許輸入兩個列表的列表項，然後使用不同的集合返回列表。

# Difference Between two Lists

list1 = []
listNumber = int(input("Enter the Total List Items = "))
for i in range(1, listNumber + 1):
    listValue = int(input("Enter the %d List Item = " %i))
    list1.append(listValue)

list2 = []
listNumber = int(input("Enter the Total List Items = "))
for i in range(1, listNumber + 1):
    listValue = int(input("Enter the %d List Item = " %i))
    list2.append(listValue)

print("First  List Items = ", list1)
print("Second List Items = ", list2)

actualdiff = list(list(set(list1) - set(list2)) + list(set(list2) - set(list1)))
print("List Difference Result = ", actualdiff)

Python 列表差異輸出

Enter the Total List Items = 3
Enter the 1 List Item = 1
Enter the 2 List Item = 2
Enter the 3 List Item = 3
Enter the Total List Items = 4
Enter the 1 List Item = 4
Enter the 2 List Item = 5
Enter the 3 List Item = 2
Enter the 4 List Item = 1
First  List Items =  [1, 2, 3]
Second List Items =  [4, 5, 2, 1]
List Difference Result =  [3, 4, 5]

在這個 Python 程序中，我們使用 for 循環和 if 語句來檢查這兩個列表之間的差異。for 循環(列表 1 +列表 2 中的 val)迭代列表 1 和列表 2 中的所有值。if 語句和 not in 運算符(if val 不在列表 1 中或 val 不在列表 2 中)檢查項目是否不在列表 1 或列表 2 中。如果為真，則將該項目追加或添加到列表差異中。

# Difference Between two Lists
list1 = [1, 2, 6, 8, 11, 14]
list2 = [2, 3, 11, 9, 7, 14, 22]

print("First  List Items = ", list1)
print("Second List Items = ", list2)

listDifference = []

for val in list1 + list2:
    if val not in list1 or val not in list2:
        listDifference.append(val)

print("List Difference Result = ", listDifference)

First  List Items =  [1, 2, 6, 8, 11, 14]
Second List Items =  [2, 3, 11, 9, 7, 14, 22]
List Difference Result =  [1, 6, 8, 3, 9, 7, 22]

這個 Python 程序使用列表理解來檢查兩個給定的列表之間的差異。

# Difference Between two Lists

list1 = [3, 4, 6, 7, 8, 11, 22]
list2 = [1, 3, 5, 11, 8, 9, 16, 44]

print("First  List Items = ", list1)
print("Second List Items = ", list2)

listdiff = [x for x in list1 + list2 if x not in list1 or x not in list2]

print("List Difference Result = ", listdiff)

First  List Items =  [3, 4, 6, 7, 8, 11, 22]
Second List Items =  [1, 3, 5, 11, 8, 9, 16, 44]
List Difference Result =  [4, 6, 7, 22, 1, 5, 9, 16, 44]
