當用戶輸入鍵（整數(shù)）時如何在字典中顯示鍵（整數(shù)）string = input("Please enter a name> ")def enumerate_string(string): s = {} for i,letter in enumerate(string): s[i] = letterx = enumerate_string(string)string2 = input("enter several integers separated by a comma ")string3 = string2.split(',')if string3 in set(x): print(x[string3])

我正在更新您的部分代碼：
string2 = input("enter several integers separated by a comma ") # 0,1,2
string3 = string2.split(',') # string3 is a list of numbers but as strings
# ['0','1','2']
string3=[int(num) for num in string3] # [0,1,2]
for num in string3:
print(x.get(num))# will return the value corresponding to the key

使用這段代碼，簡單地做同樣的事情，但在最后做一個循環(huán)，并return在函數(shù)中有一個：
string = input("Please enter a name> ")
def enumerate_string(string):
s = {}
for i,letter in enumerate(string):
s[i] = letter
return s
x = enumerate_string(string)
string2 = input("enter several integers separated by a comma ")
string3 = string2.split(',')
for i in string3:
if int(i) in x:
print(x[int(i)])
示例輸出：
Please enter a name> John Doe
enter several integers separated by a comma 0,1,2
