PAT乙級練習(Python)

1. PAT-B 1001. 害死人不償命的(3n+1)猜想 (15)

n = 0
a = int(input(''))
while a!= 1:
    if(a%2==1):
        a = (3*a+1)/2
        n += 1
    else:
        a = a/2
        n += 1
print(n)        

2.PAT-B 1009. 說反話 (20)

print(" ".join(input().split()[::-1]))

3.PAT-B 1002. 寫出這個數 (20)

L = ['ling'
 
, 'yi','er', 'san', 'si', 'wu', 'liu', 'qi', 'ba', 'jiu']
a = sum(list(map(int, input())))
list_test = []
for i in str(a):
    list_test.append(L[int(i)])
for j in range(0, len(list_test)):
    if j == len(list_test)-1:
        print(list_test[j], end="")
    else:
        print(list_test[j], end=" ")
