I'll put some of my code bellow to explain the issue, but basically what I'm trying to do it to compare within a function - a string & a line that will include only that string.
I have the list as follows:
org_tasks = ['general_static ', 'host_general_static ',etc....]
which I'm passing to function with a filename (python file)
my_dict = createDictFromTaskList(ref_ver, org_tasks)
def createDictFromTaskList(prm_fl,tasks_list):
final_dict = {}
for task in tasks_list:
print getTransformedDic(prm_fl, str('CurrentTaskParams.' + task))
return final_dict
which calls:
def getTransformedDic(prm_fl,dic_name): # transforms string to dictionary
"turns dictionary values from type variable into a string"
newDic = ""
dicToChange = getOldDicAsString(prm_fl,dic_name)
if dicToChange is None: return None
dicToChange = dicToChange[len(dic_name) + 3:] #here i get none for some reason
dicToChange = dicToChange.replace('"', "'")
for line in dicToChange.splitlines():
transformedLine = ''.join(line.split())
transformedLine = transformedLine.strip()
if transformedLine.startswith('#'): continue
IsLineBelongsToDic = transformedLine.split(':')
if len(IsLineBelongsToDic) > 1:
if transformedLine[-1:] == ",":
valueAsString = '"%s",' % transformedLine[len(IsLineBelongsToDic[0]) + 1:-1]
else:
valueAsString = '"%s",' % transformedLine[len(IsLineBelongsToDic[0]) + 1:]
line = ' ' + IsLineBelongsToDic[0] + ' : ' + valueAsString
newDic += '%s' % line + '\n'
try:
value = ast.literal_eval(newDic[:-1])
except SyntaxError:
return None
else:
return value
def getOldDicAsString(prm_fl, dic_name):
"return a string that contains dictionary"
with open(prm_fl) as f:
file_data = f.read()
recordLines = False
dictionary = ""
for line in file_data.splitlines():
transformedLine = ''.join(line.split())
transformedLine = transformedLine.strip()
taskName = transformedLine.split('=')[0]
print taskName ,dic_name # here i can see they are the same
if taskName == dic_name or recordLines:
recordLines = True
dictionary += line + '\n'
if transformedLine == "}":
return dictionary
the file i work with looks as follows (according to list I've mentioned before):
...
CurrentTaskParams.general_static = {
'is_enable' : 'true'
}
CurrentTaskParams.host_general_static = {
'is_enable' : 'true'
}
...
after adding few prints I've seen that when for example I compare
CurrentTaskParams.general_static
--> which was passed as parameter
to the line containing this string (after striping in from spaces & '{' & '=' )
I dont append the dictionary string (meaning my 'if' returns false)
any help would be great,
thanks!
The following minimal example replicates your source data and your code block:
file_data = """
CurrentTaskParams.general_static = {
'is_enable' : 'true'
}
CurrentTaskParams.host_general_static = {
'is_enable' : 'true'
}
"""
dic_name = 'CurrentTaskParams.general_static'
for line in file_data.splitlines():
transformedLine = ''.join(line.split())
transformedLine = transformedLine.strip()
taskName = transformedLine.split('=')[0]
print("'%s'" % taskName, "'%s'" % dic_name, taskName == dic_name)
Running this it correctly picks up the line in question:
'' 'CurrentTaskParams.general_static' False
'CurrentTaskParams.general_static' 'CurrentTaskParams.general_static' True
''is_enable':'true'' 'CurrentTaskParams.general_static' False
'}' 'CurrentTaskParams.general_static' False
'CurrentTaskParams.host_general_static' 'CurrentTaskParams.general_static' False
''is_enable':'true'' 'CurrentTaskParams.general_static' False
'}' 'CurrentTaskParams.general_static' False
With a working example it is difficult to debug the problem(!) but I suspect this means the problem is somewhere else.
In your example code you list the org tasks with the trailing space still in place, is this intentional?
org_tasks = ['general_static ', 'host_general_static ',etc....]
I would suggest you try printing the data you believe to be matching but wrapped in quotes (see above) as this will help better highlight any leading/trailing spaces in your strings.

Let's say I've got this code in python:
total=0for i in range(100):print(i)if i > 50:total=total+i
How would I make an algorithm in python to format this python code into the code below:
total=0
for i in range(100):
print(i)
if i > 50:
total=total+i
Assume that everything is nested under each other, such that another statement would be assumed to be inside the if block.
This was quite a fun exercise! I'm running out of juice so just posting this as is. It works on your example but probably not much for anything more complex.
code_block = "total=0for i in range(100):print(i)if i > 50:total=total+iprint('finished')"
code_block_b = "def okay() {print('ff')while True:print('blbl')break}"
line_break_before = ['for', 'while', 'if', 'print', 'break', '}']
line_break_after = [':', '{']
indent_chars = [':', '{']
unindent_chars = ['}']
# Add line breaks before keywords
for kw in line_break_before:
kw_indexes = [idx for idx in range(len(code_block)) if code_block[idx:idx + len(kw)] == kw]
for kw_idx in kw_indexes[::-1]:
code_block = code_block[:kw_idx] + '\n' + code_block[kw_idx:]
# Add line breaks after other keywords if not present already
for kw in line_break_after:
kw_indexes = [idx for idx in range(len(code_block)) if code_block[idx:idx + len(kw)] == kw]
for kw_idx in kw_indexes[::-1]:
if code_block[kw_idx + 1: kw_idx + 2] != '\n':
code_block = code_block[:kw_idx + 1] + '\n' + code_block[kw_idx + 1:]
# Add indentation
indent = 0
formatted_code_lines = []
for line in code_block.split('\n'):
if line[-1] in unindent_chars:
indent = 0
formatted_code_lines.append(' ' * indent)
if line[-1] in indent_chars:
indent += 4
formatted_code_lines.append(line + '\n')
code_block = ''.join(formatted_code_lines)
print(code_block)
The basic premise for formatting is based around keywords. There are keys that require a line break before, and keys that require a line break after them. After that, the indentation was counted +4 spaces for every line after each : symbol. I tested some formatting with braces too in code_block_b.
Output a
total=0
for i in range(100):
print(i)
if i > 50:
total=total+i
Output b
def okay() {
print('ff')
while True:
print('blbl')
break
}
I want to write an INI file with duplicate options,ie:
[test]
foo = value1
foo = value2
xxx = yyy
With ConfigParser.set only the last value is writed.
config = ConfigParser.ConfigParser()
config.read('example.cfg')
config.add_section('test')
config.set('test', service['foo'], service['value1'])
config.set('test', service['foo'], service['value2'])
config.set('test', service['xxx'], service['yyy'])
The result is:
[test]
foo = value2
xxx = yyy
Is there any way?
It looks like it isn't possible in a simple way. The default way ConfigParser stores is with dict's, i.e. one value per unique key.
In a similar question Python's ConfigParser unique keys per section the suggestions are to go with:
CongfigObj
Patched version of epydoc
i have a simple custom .ini parser in python (built for another project), which uses a list to store values but only if they are not in key=value format. if key=value then last key will be held since these are stored in a dictionary
The parser can also parse nested sections like:
[SECTION1][SECTION2]
key1=value1
; etc..
The code is below, it is easy to modify to store key/value in list instead of dictionary or even detect multiple key and rename to avoid collisions (e.g key, key$1 second key with same key value key and so on). use/modify as needed

I want to search for string in file and if there is string make action and if there isn´t string make other action, but from this code:
itcontains = self.textCtrl2.GetValue()
self.textCtrl.AppendText("\nTY: " + itcontains)
self.textCtrl2.Clear()
pztxtflpath = "TCM/Zoznam.txt"
linenr = 0
with open(pztxtflpath) as f:
found = False
for line in f:
if re.search("\b{0}\b".format(itcontains),line):
hisanswpath = "TCM/" + itcontains + ".txt"
hisansfl = codecs.open(hisanswpath, "r")
textline = hisansfl.readline()
linenr = 0
ans = ""
while textline <> "":
linenr += 1
textline = hisansfl.readline()
hisansfl.close()
rnd = random.randint(1, linenr) - 1
hisansfl = codecs.open(pztxtflpath, "r")
textline = hisansfl.readline()
linenr = 0
pzd = ""
while linenr <> rnd:
textline = hisansfl.readline()
linenr += 1
ans = textline
hisansfl.close()
self.textCtrl.AppendText("\nTexter: " + ans)
if not found:
self.textCtrl.AppendText("\nTexter: " + itcontains)
wrtnw = codecs.open(pztxtflpath, "a")
wrtnw.write("\n" + itcontains)
wrtnw.close
If there is not that string it is working corectly, but if there is that string, what i am searching for it makes if not found action. I really don´t know how to fix it, i have already try some codes from other sites, but in my code it doesn´t works. Can somebody help please?
Are you saying that the code underneath the following if statement executes if the string contains what you're looking for?
if re.search("\b{0}\b".format(itcontains),line):
If so, then you just need to add the following to the code block underneath this statement:
found = True
This will keep your if not found clause from running. If the string you are looking for should only be found once, I would also add a break statement to your first statement to break out of the loop.
! # $ % & ( ) * , - 0 / : < = > ? # [ \ ] ^

Can anybody can help me? Sometimes my file content contains some spaces but I have added this unigram_list[i]=unigram_list[i].lstrip().rstrip() but still my header contains spaces.
I ran into a similar problem with my program the other day, and I realized the easiest thing to do is ato write a simple if statement and just create a new string/list:
aStr = "Hello World this is a test!"
newStr = ""
for letter in aStr:
if letter!=" ":
newStr += letter
And when I print the newStr:
