如何输入字母(a,b或c),然后将结果打印为int。(5 * 1)而不是str? (5 * a)。
number = int(input("Input a number: "))
letter = input("Input a latter: ")
a = 1
b = 5
c = 3
print(number * letter)

您可以在此处使用字典,如下所示:
代码:
number = int(input('Enter a number: '))
letter = input('Enter a letter: ')
dict = {'a':1,'b':5,'c':3}
print( number * dict[letter.lower()])
答案 1 :(得分:0)
你可以试试这个:
number = int(input('Input a number: '))
letter = input('Input a letter: ')
a = 1
b = 5
c = 3
letter = letter.lower()
if letter in 'abc':
idx = 'abc'.index(letter)
letter = [a, b, c][idx]
print(number * letter)
要获得更灵活的方式,您可以这样做:
number = int(input('Input a number: '))
letter = input('Input a letter: ')
a = 1
b = 5
c = 3
d = 4
letter = letter.lower()
# locals() returns a dict of all variables in the current scope.
v = locals().get(letter)
if v is None:
print('"%s" is not an expected choice!' % letter)
else:
print(number * v)
