Recursive Function

[sridhar]

Hi all ,
This is going to be crazy but I need to know how to do it. Please help me out folks.

The code which I'm using is not in a proper optimized way. Can anyone help me out in writing optimised code of it. (that is using recursive functions,etc..)

Here is my code:
NestedVariable is going to search from meta_data and it is type dict which I created already which act as input

         table1 = NestedVariable.text
            if "Expression" in table1:
                inner_selist = re.findall(r"Expression\('(.*?)'\)",table1.strip())
                if inner_selist:
                    inner.append({"Level0" : inner_selist})
                    for element in inner_selist:
                        for key,value in meta_data.items():
                            if key == element:
                                in_se = key
                                if "Expression" in value:
                                    inner_selist1 = re.findall(r"Expression\('(.*?)'\)",value.strip())
                                    if inner_selist1:
                                        inner.append({"Level1_": inner_selist1})
                                        for element in inner_selist1:
                                            for key1,value1 in meta_data.items():
                                                if key1 == element:
                                                    in_se1 = key1
                                                    if "Expression" in value1:
                                                        inner_selist2 = re.findall(r"Expression\('(.*?)'\)",value1.strip())
                                                        if inner_selist2:
                                                            inner.append({"Level2_" : inner_selist2})
                                                            for element in inner_selist2:
                                                                for key2,value2 in meta_data.items():
                                                                    if key2 == element:
                                                                        in_se2 = key2
                                                                        if "Expression" in value2:
                                                                            inner_selist3 = re.findall(r"Expression\('(.*?)'\)",value2.strip())
                                                                            if inner_selist3:
                                                                                inner.append({"Level3_" : inner_selist3})
                                                                                for element in inner_selist3:
                                                                                    for key3,value3 in meta_data.items():
                                                                                        if key3 == element:
                                                                                            in_se3 = key3
                                                                        else:
                                                                            level = 'level3'
                                                        
                                                    else:
                                                        level = 'level2'
                                    
                                else:
                                    level = 'level1'
                        
            else:
                level = 'level0'

Hope y'll understand my problem here.

Thanks in advance!
