Python mange with liste

[Bala Ji]

Hello guys,
i need some help with is program

I have a txt file "test.txt" where there is Name;Sexe;Answer(Y or N)
example of txt file:
--------------------------------------
nam1;F;Y
nam2;M;N
nam3;F;Y
nam4;M;N
halo;M;Y
rock;M;N
nam1;F;N
_________________________________

so my program will ask the name, sexe, and answer and it will tell me if the name exist or not

example i will enter
nam1;F;O

The program must tell me that nam1 with sexe F existe. (it must take in count the answer)

------------------------------------------------
name = raw_input('name: ')
sexe = raw_input('sexe: ')
r1 = raw_input('r1 Y or N: ')
infos = name+";"+sexe+";"+r1

f=open("test.txt","r")
conten = f.read()
print conten
f.close()

	#f=open("test.txt","a")
	#f.write(infos)
	#f.write('\n')
	#f.close()
------------------------------------------------

thank you =)
