I am trying to separate all the images from the following string.
how can I get a list of images that start with "comp1/img_" and are either split by a "," or a ";"
/*jsonp*/jsonresp({"img_set":"comp1/img_23434;comp1/img_3243r43r,comp1/img_o43nfjr;comp1/img_wjfno43,comp1/img_nrejfner;comp1/img_jrenckerjv,comp1/img_23434k;comp1/img_rkfnk4n"},"fknreff\",");
so I would end up with a list like...
comp1/img_23434
comp1/img_3243r43r
comp1/img_o43nfjr
comp1/img_wjfno43
comp1/img_nrejfner
comp1/img_jrenckerjv
comp1/img_23434k
comp1/img_rkfnk4n
any help would be appreciated.
thanks

You can do this:
>>> data = '/*jsonp*/jsonresp({"img_set":"comp1/img_23434;comp1/img_3243r43r,comp1/img_o43nfjr;comp1/img_wjfno43,comp1/img_nrejfner;comp1/img_jrenckerjv,comp1/img_23434k;comp1/img_rkfnk4n"},"fknreff\",");'
>>> import re
>>> re.findall(r'comp1/img_[^;,"]+', data)
['comp1/img_23434', 'comp1/img_3243r43r', 'comp1/img_o43nfjr', 'comp1/img_wjfno43', 'comp1/img_nrejfner', 'comp1/img_jrenckerjv', 'comp1/img_23434k', 'comp1/img_rkfnk4n']

How can I build a nested dictionary from reading configure files in Python, such that I can access it like this:
multi_dict["name1"]["name2"]["name3"] = some_value
My current approach is:
if name1 not in dict:
dict["name1"] = {}
dict["name1"]["name2"] = {}
(etc.)
But this ways seems so boring! Is there a more elegant way to do this?
The configure files that I'm reading are like the following:
[a1]
key1=value1
[a2]
[.a3]
key2=value2
[..a4]
key3=value3
The . prefixes mean "another level of nesting". So in this example, I would set:
dict[a1][key1]=value1
dict[a2][a3][key2]=value2
dict[a2][a3][a4][key3]=value3

I have a text file where I wrote a list of symbolic equations. I need to set the value of a variable with this list.
In other words I'm looking for a command that automatically "copy" all I have written in the text file and "paste" it into an expression such this:
a = all_it's_written_in_the_text_file
Is this possible?

with open(filename, "rt") as f:
a = eval(f.read())

I need to write a regex, that will traverse through my file and replace each :
href='#!/api/API.
with
href='http://www.domain.com/API. . I currently have this kind of code, that will be run from console :
def replace(file, pattern, substring):
my_file = open(file)
for line in my_file:
my_file.write(line.replace(pattern, substring))
Will sending the given strings work in this case ?

So you want to replace #!/api with http://www.domain.com?
You can just do:
line.replace('#!/api','http://www.domain.com')
No need for regex.
