If condition in for loop for two variable

I have a data file named st and it contains many lines of variables and each line of them has the specific name. I want to select two specific lines of those data with names and assigned them to values. My codes are as bellow and it just selects one line of my data and ignores the second 'if' condition. Does anybody have an Idea?

with open(input("ENTER YOUR STATIONS COORDINATES FILE NAME : "), 'r') as st:
    ST = input("ENTER YOUR STATION NAME :").upper()
    ST1 = input("ENTER YOUR 00 STATION NAME :").upper()
    with open(input("ENTER YOUR COORDINATE FILE NAME :"), 'r') as f1:
        with open(input("ENTER YOUR OUTPUT FILE NAME :"), 'w') as f2:
            print(ST, ST1)
            for lines in st:
                values = lines.split()
                NO = int(values[0])
                X = float(values[1])
                Y = float(values[2])
                Z = float(values[3])
                Code = values[4]
                if Code == ST:
                    X1 = float(values[1])
                    Y1 = float(values[2])
                    print(X1, Y1)
                    if Code == ST1:
                        X00 = float(values[1])
                        Y00 = float(values[2])
                        print(X1, Y1, X00, Y00)
                        st.close()

A part of My input data:

1      1505.114      5528.524   1060.572   S1
2      1283.787      5442.505   1084.851   S3
3      1189.962      5272.845   1108.214   S3t1

My code output as is below:

ENTER YOUR STATIONS COORDINATES FILE NAME: st
ENTER YOUR STATION NAME:s3t2
ENTER YOUR 00 STATION NAME:s3
ENTER YOUR COORDINATE FILE NAME:h.dat
ENTER YOUR OUTPUT FILE NAME:h.out
S3T2 S3
