我试图制作一个函数,将多个变量与一个整数进行比较,并输出一个三个字母的字符串。我想知道是否有办法将其翻译成Python。所以说:

x = 0
y = 1
z = 3
mylist = []

if x or y or z == 0:
    mylist.append("c")
if x or y or z == 1:
    mylist.append("d")
if x or y or z == 2:
    mylist.append("e")
if x or y or z == 3: 
    mylist.append("f")

其将返回以下列表:

["c", "d", "f"]

当前回答

要使用一个值测试多个变量:如果{a,b,c}中为1:

要使用一个变量测试多个值:如果{1,2,3}中有一个:

其他回答

要针对单个值测试多个变量,请执行以下操作:

将变量包装在集合对象中,例如{a,b,c}。使用in运算符测试值是否存储在任何变量中。如果值存储在至少一个变量中,in运算符将返回True。

# ✅ test multiple variables against single value using tuple

if 'a' in (a, b, c):
    print('value is stored in at least one of the variables')

# ---------------------------------------------------------

# ✅ test multiple variables against single value using tuple

if 'a' in {a, b, c}:
    print('value is stored in at least one of the variables')

# ---------------------------------------------------------


# ✅ test multiple variables against single value (OR operator chaining)
if a == 'a' or b == 'a' or c == 'a':
    print('value is stored in at least one of the variables')

此代码可能有帮助

L ={x, y, z}
T= ((0,"c"),(1,"d"),(2,"e"),(3,"f"),)
List2=[]
for t in T :
if t[0] in L :
    List2.append(t[1])
    break;
d = {0:'c', 1:'d', 2:'e', 3: 'f'}
x, y, z = (0, 1, 3)
print [v for (k,v) in d.items() if x==k or y==k or z==k]

要使用一个值测试多个变量:如果{a,b,c}中为1:

要使用一个变量测试多个值:如果{1,2,3}中有一个:

如果您想使用If,else语句,下面是另一种解决方案:

myList = []
aList = [0, 1, 3]

for l in aList:
    if l==0: myList.append('c')
    elif l==1: myList.append('d')
    elif l==2: myList.append('e')
    elif l==3: myList.append('f')

print(myList)
