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"]

还有一种方法：
x = 0
y = 1
z = 3
mylist = []
if any(i in [0] for i in[x,y,z]):
mylist.append("c")
if any(i in [1] for i in[x,y,z]):
mylist.append("d")
if any(i in [2] for i in[x,y,z]):
mylist.append("e")
if any(i in [3] for i in[x,y,z]):
mylist.append("f")
它是列表理解和任何关键字的混合。
其他回答
您可以尝试下面显示的方法。在该方法中，您可以自由指定/输入要输入的变量数量。
mydict = {0:"c", 1:"d", 2:"e", 3:"f"}
mylist= []
num_var = int(raw_input("How many variables? ")) #Enter 3 when asked for input.
for i in range(num_var):
''' Enter 0 as first input, 1 as second input and 3 as third input.'''
globals()['var'+str('i').zfill(3)] = int(raw_input("Enter an integer between 0 and 3 "))
mylist += mydict[globals()['var'+str('i').zfill(3)]]
print mylist
>>> ['c', 'd', 'f']
您的问题更容易通过字典结构解决，如：
x = 0
y = 1
z = 3
d = {0: 'c', 1:'d', 2:'e', 3:'f'}
mylist = [d[k] for k in [x, y, z]]
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]
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)
如果没有dict，请尝试以下解决方案：
x, y, z = 0, 1, 3
offset = ord('c')
[chr(i + offset) for i in (x,y,z)]
并给出：
['c', 'd', 'f']
