Problem with For "str" in str["str"]

Tarik EL JABIRI

Hi,
I have a List like this :

myList = [
 "LOT_1,T49359/22",
 "LOT_2,T49360/22",
 "LOT_3,T49361/22",
 "LOT_4,T49362/22",
 "LOT_5,T49363/22",
 "LOT_6,T49364/22",
 "LOT_7,T49365/22",
 "LOT_8,T49366/22",
 "LOT_9,T49367/22",
 "LOT_10,T49368/22",
 "LOT_11,T49369/22",
 "LOT_12,T49370/22",
 "LOT_13,T49371/22",
 "LOT_14,T49372/22",
 "LOT_15,T49373/22",
       "..."
 "LOT_995,T50125/22"]

and i have folders like this: C:/subfolder/subfolder1/LOT_830 folders from LOT_1 to LOT_995.
My code Source is :

for f in subfolders:
 
    folder_is_not_renamed = True
 
    for line in myList:
        result = line.replace("\n", "").replace("/", "-").split(",")
        if result[0] in f:
            myDirectory = f.replace(os.path.dirname(f), "")
 
            # src source
            src = f
            # dist distination
            dist = f.replace(myDirectory, '/' + result[1])
 
            if not os.path.exists(dist):
 
                os.rename(src, dist)
                 
                folder_is_not_renamed = False
    if folder_is_not_renamed:
        print(f + " is not Renamed \n")
print('Finished')

the problem is when it arrives to folder "C:/subfolder/subfolder1/LOT_10" the "if result[0] in f" return True for LOT_1 but not the case it should return False. I know that "LOT_1" in "C:/subfolder/subfolder1/LOT_10" return True it is correct but i want a way to avoid it.

I want to mention some folders contains like "C:/subfolder/subfolder1/LOT_10 BIS" or something else.
I am always looking for LOT_10 no matter what after it or before it.

thank you.

@tarik-el-jabiri here is a non-coded rendition of a method to deal with this issue -- it might not be the best and then again it might just be -- it is basically I would at least initially handle this situation.

First I would convert myList into myDict arranged as follows:

Key = 'LOT_1'  Value = 'T49359/22'

or in Dictionary nomenclature

{'LOT_1':'T49359/22'
 ...
}

Next instead of working with the raw Folder Names run them through a preprocessor so that you can apply your business rules to that folder (aka business rules such as LOT_1 <> LOT_10, etc...)

Then Pass the foldername into your preprocessor routine and have that routine return a Key:Value where:

Key = 'LOT_???'   Value = 'Full_Folder_Path_Name'

Then you can do something as easy as

for FolderKey in ReturnedValue:
    if FolderKey in myDict.keys():
        FolderValue = ReturnedValue[FolderKey]

        Now you have the two values you are looking for already separated

As for the Preprocessor Routine you are going to have to basically search for 'LOT_' and then because your number can be up to 3 digits grab the next 3 characters and determine what number you actually have discarding anything that is not a number. Numerous ways to do this for instance you could try to convert each character to a number and add them together such as:

if isnumeric(String[0]):
   digit = int(String[0]

   if isnumeric(String[1]):
       digit = (digit * 10) + int(String[1]

       if isnumeric(String[2]):
           digit = (digit * 10) + int(String[2]
           
NewValue = 'LOT_' + str(digit)

I nested these because if you run into a non-integer followed by an integer you do not get the wrong end result
