谁能想出一个简洁的python代码来定义键和值?

Question

如果我们将任意键作为输入，我们应该得到相应的值作为输出;如果我们将列表中的任意一个元素作为输入，我们应该得到相应的键作为输出。请忽略中间的enter code here

以下是键及其值

"RCB": ["Virat";Abd"， "Maxwell"，"Chahal"]，"CSK"; [" doni "， "Raina"， "Jadeja"， "Faf"]["Morgan"， "Russell"， "Karthik"， "Naenter code hereine"]"PBKS":【"Rahul","Mayank","Shami","Gayle"]

Answer 1

我相信这就是你想要的:

dict = {
"RCB" : ["Virat", "Abd", "Maxwell","Chahal"], 
"CSK": ["Dhoni", "Raina", "Jadeja", "Faf"],
"KKR": ["Morgan", "Russell", "Karthik", "Naenter code hereine"],
"PBKS" : ["Rahul", "Mayank", "Shami", "Gayle"]
}
def getOutput(dict, value):
try:
output = dict[value]
return output
except KeyError:
for key in dict:
if value in dict[key]:
output = key
return output
return None
print(getOutput(dict, "RCB")) 
#["Virat", "Abd", "Maxwell","Chahal"]
print(getOutput(dict, "Raina"))
#"CSK"
