为什么会出现这种结果

Question

playerlevel = 1
playerattack = 10
playerhealth = 100
playerexp = 0

print (playerlevel)
answer = input('have you played before? yes or no: ')
if answer == 'yes':
    level = input('what was your level: ')
    playerlevel *= level
    playerattack *= level
playerhealth *= level
else:
    pass

print ("player level: %s" % playerlevel)
print ("player health: %s" % playerhealth)
print ("player attack: %s" % playerattack)
print ("player exp: %s" % playerexp)

当我运行这个程序时，它运行玩家等级如果等级为2它打印2但其他打印 - ＆gt;每个222222222222222222222222222222222。为exp 0

Answer 1

level = input('what was your level: ')

input返回一个字符串*。将字符串乘以整数时，会多次重复该字符串。例如，"2" * 3为"222"。

如果你想要实际的数字乘法，在使用之前将等级转换为整数。

level = int(input('what was your level: '))

_{*仅适用于Python 3.X. input可以返回2.7及更低版本中的其他类型，但您应该在这些版本中使用raw_input。}
