How to join nested list of strings and get the result as new list of string?

Question

I am having nested list of strings as:

A = [[\"A\",\"B\",\"C\"],[\"A\",\"B\"]]

I am trying to join the strings in sublist to get a single l

I wrote these and found them very useful in my case, you can adapt them to your needs ...

First one is to flatten nested list but not loose degree of nestedness by using tabs '\t'. Second one clears tabs and empty lines'.

def nested2str(s,d):
    isNested=False;
    for i in s:
        if type(i)==list:
            isNested=True;

    if isNested==False:
        t=''
        for i in s:
            t=t+'\t'*d+i+'\n'
        return t

    for i in range(len(s)):
        if type(s[i])==list:
            s[i]=nested2str(s[i],d+1)

    t=''
    for i in s:
        t=t+'\t'*d+i+'\n'
    return t

def clearStr(s):
    for i in range(10):
        s=s.replace('\n\n','\n')
        return s.replace('\n\n','\n').replace('\t','')

I have a nested variable :

print(temp)                                                                                                              
['gediz i5\n', 'Wan İp', 'Lan Ip', ['Model name:          Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz'], ['CPU(s):              4'], 'RAM: 15.6GB', ['01:00.0 VGA compatible controller: NVIDIA Corporation TU104 [GeForce RTX 2070 SUPER] (rev a1)'], ['disk TOSHIBA-TR200    447,1G', 'disk KINGSTON SHFS37A 111,8G', 'disk SAMSUNG HD103SJ  931,5G']]

It modifies temp, if you only use nested2str:

print(nested2str(temp,0)))
gediz i5

Wan ip
Lan ip
    Model name:          Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz

    CPU(s):              4

RAM: 15.6GB
    01:00.0 VGA compatible controller: NVIDIA Corporation TU104 [GeForce RTX 2070 SUPER] (rev a1)

    disk TOSHIBA-TR200    447,1G
    disk KINGSTON SHFS37A 111,8G
    disk SAMSUNG HD103SJ  931,5G

If you use both:

print(clearStr(nested2str(temp,0)))                                                                                      
gediz i5
Wan Ip
Lan Ip
