编写完函数,继续往下编写准备,刚写一行就报错了

Question

>>> def in_fridge():

try:
    count = fridge[wanted_food]
except KeyError:
    count = 0
return count
fridge = {"apples":3,"pear":4}

写到最后一行报错是:
SyntaxError: invalid syntax

Answer 1

简单地来说，就是格式有问题，用个IDE应该就能看清楚了。

pythondef in_fridge():
    try:
        count = fridge[wanted_food]
    except KeyError:
        count = 0
    return count

fridge={"apples": 3, "pear": 4}

Answer 2

楼主要的是这个意思？如下：

>>> def in_fridge():
...     try:
...         count = fridge[wanted_food]
...     except KeyError:
...         count = 0
...     return count
... 
>>> fridge = {"apples": 3, "pear": 4}

Answer 3

ipython中，需要自己按tab键或者空格键来进行正确的缩进的，而主流的编辑器是自动给你加的
