I have a variable that looks like this:
data = {"add_content": {"errata_ids": [advisory]},"content_view_version_environments": [{"content_view_version_id": version_id}]}
I need to add single quotes to this variable , i.e. if I will assign the variables:
advisory and version_id and add the single quotes to data variable like this:
data = '{"add_content": {"errata_ids": ["RHSA-2017:1390"]},"content_view_version_environments": [{"content_view_version_id": 160}]}'
I am able to post to the API
I have tried to add the single quotes in variety of ways:
new_data = "'" + str(data) + "'"
>>> new_data
'\'{\'add_content\': {\'errata_ids\': [\'"RHSA-2017:1390"\']}, \'content_view_version_environments\': [{\'content_view_version_id\': \'160\'}]}\''
or using:
'"%s"'%(data)
and a few more ways.
How can I add the single quotes to the outer to the data variable before and after the opening { and closing }?
This is exactly what JSON does:
import json
new_data = json.dumps(data)
If in contrary of previous answers and comments you are not trying to convert to a json string then use string.format around the variables:
data = {"add_content": {"errata_ids": '[{}]'.format(advisory)},"content_view_version_environments": [{"content_view_version_id": '{}'.format(version_id)}]}

I have a sql query string
query_for_update =
f'''
update {db_name}.{schema_name}.{self.table_name}
set {self.updated_field} = {self.updated_field}
where {self.key_field} in ({ids});
'''
But when I try to write this query to file f.write(query_for_update) I get following result:
update store_1.dbo.[my_table]
set [Trusted Plan] = [Trusted Plan]
where [Entry No_] in (1472371,
1472375,
1472377,
1472379,
1472373,
);
Code that creates string:
ids_string = ',\n'.join(["'" + str(item) + "'" for item in result.id])
query_for_update = mssql_table.get_update_query('dbo', mssql_db_name, ids_string).strip()
with open(mssql_server_name + '.sql', 'a') as f:
f.write(query_for_update)
How can i remove indents for strings in this case?
You can use textwrap.dedent (standard library):
import textwrap
query = textwrap.dedent(f"""\
update {db_name}.{schema_name}.{self.table_name}
set {self.updated_field} = {self.updated_field}
where {self.key_field} in ({ids});
""")
print(query)
This will remove all leading spaces that are common between every line. Useful for tipple quoted strings.
You can use the str.strip() function with a for loop to fix it.
for x in list:
if x.strip():
list2.append(x)
then you can use list2 as your new usable list
you can use the str.stip method https://www.w3schools.com/python/ref_string_strip.asp
For indentations and breaks you need to consider that you might need to use \n. There is also a dedent method in the textwrap library that could be interesting for you. https://docs.python.org/3/library/textwrap.html
I hope this helps :)

Is this obtainable with python? And what do i need to do to achieve the wanted end result?
if your paraneters are separated by newlines you can use the splitlines method to get a list of parameters, and use re.split on each item to get a list with name, value.
Then apply quote_plus on each name and value, '='.join them and '&'.join all parameters.

data = [re.split(':(?!//)', line) for line in data.splitlines()]
data = '&'.join('='.join(urllib.parse.quote_plus(i) for i in l) for l in data)
If your data is split by newlines arbitrarily, you could join the lines and split by name. Then zip names and values, quote and join.
data = ''.join(data.splitlines())
data = zip(['PaReq', 'TermUrl', 'MD'], re.split('PaReq:|TermUrl:|MD:', data)[1:])
data = '&'.join('='.join(urllib.parse.quote_plus(i) for i in l) for l in data)
If you want to keep the newline cheracter, use only the last two lines in the second code snippet.
I want to convert a string into a dictionary. I saved this dictionary previously in a text file.
The problem is now, that I am not sure, how the structure of the keys are. The values are generated with Counter(dictionaryName). The dictionary is really large, so I cannot check every key to see how it would be possible.
The keys can contain simple quotes like ', double quotes ", commas and maybe other characters. So is there any possibility to convert it back into a dictionary?
For example this is stored in the file:
Counter({'element0':512, "'4,5'element1":50, '4:55foobar':23,...})
I found previous solutions with for example json, but I have problems with the double quotes and I cannot simply split for the commas.
If you trust the source, load from collections import Counter and eval() the string
How about something like:
>> from collections import Counter
>> line = '''Counter({'element0':512, "'4,5'element1":50, '4:55foobar':23})'''
>> D = eval(line)
>> D
Counter({"'4,5'element1": 50, '4:55foobar': 23, 'element0': 512})
You could remove the Counter( and ) parts, then parse the rest with ast.literal_eval as long as it only involves basic Python data types:
import ast
def parse_Counter_string(s):
s = s.strip()
if not (s.startswith('Counter(') and s.endswith(')')):
raise ValueError('String does not match expected format')
# Counter( is 8 characters
# 12345678
s = s[8:-1]
return Counter(ast.literal_eval(s))
In the future, I recommend picking a different way to serialize your data.
you can use demjson library for doing this, you can have the text directly in your program
import demjson
counter = demjson.decode("enter your text here")
if it is in the file ,you can do the following steps :
WD = dirname(realpath(__file__))
file = open(WD, "filename"), "r")
counter = demjson.decode(file.read())
file.close()
Id like to know what it takes to remove a comma from the last line within a for loop in python. When I run the script it gives me the below output(after code section). I want to remove the comma at the end of fourth line "{"{#MACRO}":"queue4"}," Please can someone help?
By the way if there is a better way to construct the block please share the ideas. I'm a beginner and like to learn. :)
Code:
import json
import urllib
import string
Url= "http://guest:guest#localhost:55672/api/queues"
Response = urllib.urlopen(Url)
Data = Response.read()
def Qlist(Name):
Text = ''' {{"{{#MACRO}}":"{Name}"}},'''.format(Name=Name)
print Text
X_json = json.loads(Data)
print '''{
"data":['''
for i in X_json:
VV = i['name']
Qlist(VV)
print ''']
}'''
Below is the Output:
{
"data":[
{"{#MACRO}":"queue1"},
{"{#MACRO}":"queue2"},
{"{#MACRO}":"queue3"},
{"{#MACRO}":"queue4"},
]
}
Thanks so much
You can modify your loop as follows.
# Create and initialize a dictionary (Associative Array)
# data['data'] is an empty list.
# Variable name (data in this case) can be anything you want.
# 'data' is a key. notice the quotations around. it's not a variable.
# I used 'data' as the key, becasue you wanted your final output to include that part.
data = {"data": []}
for i in X_json:
# We are not calling the data dictionary here.
# We are accessing the empty list we have created inside the `data` dict (above) using data['data'] syntax.
# We can use the append function to add an item to a list.
# We create a new dictionary for every `name` item found in your json array and
# append that new dictionary to the data['data'] list.
data['data'].append({"{#MACRO}": i['name']})
print(json.dumps(data))
# or print json.dumps(data, indent=True)
Read more about json.dumps() here. You can read more about python's list and dictionary here
Don't print inside Qlist - instead return a value; then you can join all returned values using comma as separator:
def Qlist(Name):
Text = ''' {{"{{#MACRO}}":"{Name}"}}'''.format(Name=Name)
return Text
print '''{
"data":[''' +
',\n'.join([ Qlist(i['name']) for i in X_json ]) +
''']
}'''
And anyway, using json.dumps is likely a better idea.
I'm currently trying to convert a table into RDF using Python and attach the values from each cell to the end of a URL (eg E00 becomes statistics.data.gov.uk/id/statistical-geography/E00).
I can do this for cells containing a single value using the script.
FirstCode = row[11]
if row[11] != '':
RDF = RDF + '<http://statistics.data.gov.uk/id/statistical-geography/' + FirstCode + '>.\n'
One field within the database contains multiple values that are comma delimited.
The code above therefore returns all the codes appended to the URL
e.g. http://statistics.data.gov.uk/id/statistical-geography/E00,W00,S00
Whereas I'd like it to return three values
statistics.data.gov.uk/id/statistical-geography/E00
statistics.data.gov.uk/id/statistical-geography/W00
statistics.data.gov.uk/id/statistical-geography/S00
Is there some code that will allow me to separate these out?
Yes, there is the split method.
FirstCode.split(",")
will return a list like (E00, W00, S00)
You can than iterate over the items in the list:
for i in FirstCode.split(","):
print i
Will print out:
E00
W00
S00
This page has some other useful string functions
for i in FirstCode.split(','):
RDF = RDF + '<http://statistics.data.gov.uk/id/statistical-geography/' + i + '>.\n'
