Python How to print dictionary in one line?

Question

Hi I am new to Python and I am struggling regarding how to print dictionary.

I have a dictionary as shown below.

dictionary = {a:1,b:1,c:2}

How can I print dictionary in one line as shown below?

a1b1c2

I want to print keys and values in one line but could not figure out by myself.

I would appreciate your advice!

`d = {'a':1,'b':1,'c':2}; "".join([k+str(v) for k,v in d.items()])` ? — alvas, Sep 19 '16 at 16:47
Please show your code attempt at this and explain what difficulty you are having — idjaw, Sep 19 '16 at 16:47
@idjaw I tried like this. for k, v in count.items(): print("{0}{1}".format(k, v)). But this code print values in multiple lines. — yusuke0426, Sep 19 '16 at 17:03
To fix your own code, you have to pass `end=''` in your print method. https://docs.python.org/3/library/functions.html#print — idjaw, Sep 19 '16 at 17:05

With a dictionary, e.g.

dictionary = {'a':1,'b':1,'c':2}

You could try:

print ''.join(['{0}{1}'.format(k, v) for k,v in dictionary.iteritems()])

Resulting in

a1c2b1

If order matters, try using an OrderedDict, as described by this post.

```def format_dict(dictionary): return ' '.join(['{0}={1}'.format(k, v) for k,v in dictionary.iteritems()])``` – Alon Burg Mar 26 '19 at 11:01

If you want a string to contain the answer, you could do this:

>>> dictionary = {'a':1,'b':1,'c':2}
>>> result = "".join(str(key) + str(value) for key, value in dictionary.items())
>>> print(result)
c2b1a1

This uses the join method on an empty string. Dict's are not ordered, so the order of the output may vary.

Update - Using f-strings you could do this too:

>>> result = "".join(f"{key}{value}" for key, value in dictionary.items())

Note that in Python 3.6 dicts are now ordered (unless you mess with them a lot), so the order of the output in 3.6+ will be deterministic. – Brad Campbell Apr 03 '17 at 20:26
