Replace String and ignore case Python

Question

I have problem with replace some string with upper or lower case

Its my test script:

translate=[{'NO': 'frontsplitter', 'DK': 'frontlæbe'}, {'NO': 'diffuser', 'DK': 'diffusor'}, {'NO': 'gitter', 'DK': 'grill'}, {'NO': 'lettmetallfelger', 'DK': 'letmetalfælge'}, {'NO': 'stålfelger', 'DK': 'stålfælge'}, {'NO': 'atv felger', 'DK': 'atv fælge'}, {'NO': 'dekk', 'DK': 'dæk'}, {'NO': 'motorcykeldæk', 'DK': 'Motorcykeldæk & scooterdæk'}, {'NO': 'Go-cart-dæk', 'DK': 'gokartdæk'}, {'NO': 'ophæng', 'DK': 'hjulophæng'}, {'NO': 'parhardstag', 'DK': 'parhardstang'}, {'NO': 'stabstag', 'DK': 'stabilisator'}, {'NO': 'styredempere', 'DK': 'styrdæmpere'}, {'NO': 'Støddæmper\xa0 ', 'DK': 'Støddæmpere'}, {'NO': 'tillinger', 'DK': 'bøsning'}, {'NO': 'ogre varer', 'DK': 'andre varer'}, {'NO': 'Off-road udstyr', 'DK': '4x4 tilbehør'}, {'NO': 'drivlinje', 'DK': 'transmissionsystem'}, {'NO': 'ophæng', 'DK': 'hjulophæng'}, {'NO': 'skærmtiløger', 'DK': 'Skærm-kit'}, {'NO': 'vinsjer', 'DK': 'spil'}, {'NO': 'vinsjutstyr', 'DK': 'spiludstyr'}, {'NO': 'bærbar vinsjer', 'DK': 'bærbare spil'}, {'NO': 'vinsjplater', 'DK': 'spilmonteringsplade'}, {'NO': 'afstogsstykker', 'DK': 'Afstandsstykker\n'}, {'NO': 'kofangere', 'DK': 'kofanger'}, {'NO': 'oget tilbehør', 'DK': 'Andre tilbehør'}]


def translating(string):
    print(translate)
    print(string)

    for row in translate:
        NO=row["NO"]
        DK = row["DK"]


        string=string.replace(NO,DK)
    print(string)
    return string


translating("Dekk Maxxis M8080 Mudzilla 33x13.5-15 110L")

how i can ignore case and replace word in this exaple shoud replace Dekk to dæk or when Dekk replace to Dæk and when dekk then replace to dæk

I need duplicate this on array?

Dæk Maxxis M8080 Mudzilla 33x13.5-15 110L or When string "dekk Maxxis M8080 Mudzilla 33x13.5-15 110L" then dæk Maxxis M8080 Mudzilla 33x13.5-15 110L ofc its exaple some words can be between some other words — Small Atom

It seems that you don't pay intrest in maintaining the same case for your output string.

You can simply use the

string.casefold()

option in python to remove all case distinctions present in a python string.

So this is how your function will look

def translating(string):
string = string.casefold()


for row in translate:
    NO=row["NO"]
    DK = row["DK"]


    string=string.replace(NO,DK)
print(string)

You can also use string.upper() to convert the whole string to uppercase or string.lower() to convert the whole string to lowercase and then use string.replace().But in these methods the values stored in the "NO" keys have to match with the respective case.

I would check to see if the first letter is a capital letter, if it is convert it to lower case, replace and then capitalize it again. In the case the word isn't capitalized you can just replace.

def translating(string):
        print(translate)
        print(string)

        for row in translate:
            NO=row["NO"]
            DK = row["DK"]

            if string[0].isupper() :
               string=string.lower().replace(NO,DK).capitalize()
            else:
               string=string.replace(NO,DK)

        print(string)
        return string


    translating("Dekk Maxxis M8080 Mudzilla 33x13.5-15 110L")

UPDATE

def translating(string):
    print(translate)
    print(string)

    for row in translate:
        NO=row["NO"]
        DK = row["DK"]

        if string.find(NO.capitalize()):
            string=string.replace(NO,DK.capitalize())

        string=string.replace(NO,DK)

    print(string)
    return string

The string type doesn't support this. You're probably best off using the regular expression submethod with the re.IGNORECASE option. Package for that is "re".
