if j == 'Spinach':
  print(...)
  continue

或

if j == 'Spinach':
   print("Feed it..")
else:
   print(i,j)

使用 else 除了 if ，如下所示：

proteins = ["venison", "tuna", "chicken"]
veggies = ["kale", "spinach", "tomatoes"]

for i in proteins:
    for j in veggies:
        if j == "spinach":
            print("Spinach?!? Feed it to the dog")
        else:
            print(i,j)
print(type(j))

proteins = ["venison", "tuna", "chicken"]
veggies = ["kale", "spinach", "tomatoes"]

for i in proteins:
    for j in veggies:
        if j == "spinach":
            print("Spinach?!? Feed it to the dog")
        else:
            print(i,j)

哈哈哈。。。和其他一样简单。。。愚蠢的我^ ^既然你能让事情变得复杂，为什么还要让事情变得简单？
也就是说，是否有一种方法可以以某种方式增加索引或元素？
我试过了

proteins = ["venison", "tuna", "chicken"]
veggies = ["kale", "spinach", "tomatoes"]

for i in proteins:
    for j in veggies:
        if j == "spinach":
            print("Spinach?!? Feed it to the dog")
            j=j+1
        print (I,j)

但它返回一个错误：typeerror:只能将str（而不是“int”）连接到str。
我知道i或j不是列表的索引。。。所以我想知道我该怎么做。
谢谢大家！
