How to match duplicates and if match how to remove second one in list in python?

Question

I have the list of APIs, Input = [WriteConsoleA, WSAStartup, RegCloseKey, RegCloseKey, RegCloseKey, NtTerminateProces, RegCloseKey]

expected output = [WriteConsoleA, WSAStartup, RegCloseKey, NtTerminateProces, RegCloseKey]

As I see 'RegCloseKey' element has ocurred four times in a list.SO what do you mean by second one in a list? I didn't get you expected output — SRG, Dec 27 '19 at 06:34

you can simply convert set(list) i.e. set(Input) to remove all the duplicates.

Input = ["WriteConsoleA", "WSAStartup", "RegCloseKey", "RegCloseKey", "RegCloseKey", "NtTerminateProces", "RegCloseKey"]
Output = []
api=Input[0]
for index in range(1,len(Input)):
    if api!=Input[index]:
        Output.append(api)
        api=Input[index]
Output.append(api)
print(Output)

Try this hopefully it will work in your case.
