真是假 [英] True of False
问题描述
我尝试写一个真假的If语句而且没有得到任何东西吗？我读过一些以前的帖子，但我一定不能错过
的东西。我只是尝试了一些简单的方法：
a = [" a，b，c，d，e，f]
如果c在a == True：
打印是
当我运行它时，它运行，但没有任何打印。我做错了什么？
谢谢。

I tried writing a true and false If statement and didn''t get
anything? I read some previous posts, but I must be missing
something. I just tried something easy:
a = ["a", "b", "c", "d", "e", "f"]
if "c" in a == True:
Print "Yes"
When I run this, it runs, but nothing prints. What am I doing wrong?
Thanks.

，
你可能想要包括paren（a中的c）和小写的p
打印，即打印，它应该工作
所以例如：
a = [" a，b，c，d，e，f]
if（c在a中）== True：
print" Yes"
,
You may want to include paren around ("c" in a) and a lower case p for
Print, i.e. print, and it should work
so eg:
a = ["a", "b", "c", "d", "e", "f"]
if ("c" in a) == True:
print "Yes"

哇奇怪：
在[265]中：a = list（''abcdef''）
[266]：a
Out [266]：[''a''，''b''，'c''， ''''，''e''，''f'']
在[267]中：'''''在'$ b $'中出[267]：正确
在[268]中：''c''在==真实
出[268]：错误
在[269]中:('''c''在a）==真实
Out [269]：正确
在[270]中：'''''（a == True）
----------------------- -------------------------------------------------- -
< type''exception.TypeError''Trailback（最近一次调用最后一次）
/ home / bj /< ipython consolein<模块>（）
< type''exception.TypeError''>：类型''bool''的参数不可迭代
什么'要去那儿吗？

Wow that''s odd:
In [265]: a = list(''abcdef'')
In [266]: a
Out[266]: [''a'', ''b'', ''c'', ''d'', ''e'', ''f'']
In [267]: ''c'' in a
Out[267]: True
In [268]: ''c'' in a == True
Out[268]: False
In [269]: (''c'' in a) == True
Out[269]: True
In [270]: ''c'' in (a == True)
---------------------------------------------------------------------------
<type ''exceptions.TypeError'' Traceback (most recent call last)
/home/bj/<ipython consolein <module>()
<type ''exceptions.TypeError''>: argument of type ''bool'' is not iterable
What''s going on there?
Ciao,

你好，
只需尝试：
a = [" a"，" b"，" c"，" d"，" e"" f" ;]
如果c在a：
打印是
这将作为声明''" c"在一个''本身是真的。你可以通过输入c来尝试
在翻译处。
问候，

Hello,
Just try :
a = ["a","b","c","d","e","f"]
if "c" in a:
print "yes"
That is going to work as the statement ''"c" in a'' itself is true. You
could try that by typing "c" in a at the interpreter.
