Changing text using Python

I am attempting to replace text from a source file into a new file. The replacing of text works for one line, but a few lines down and I fail to replace text sitting in the middle of a statement.

Here is the source text. The words in brackets are what I am trying to replace, without changing the characters around the words:

[set interfaces] ge-0/0/0 [description] "OoB Mgmt Connection"

This is what I would like to output:

interface x/x name "xxx" (also adding quotations for the xxx text after "name")

However the output text replaces once, and then keeps three copies of the original text:

    hostname "EX4300"
    set system host-name EX4300
    set system host-name EX4300
    set system auto-snapshot
    set system auto-snapshot
    set system auto-snapshot

Here is my code:

    with open("SanitizedFinal_E4300.txt", "rt") as fin:
         with open("output6.txt", "wt") as fout:
              for line in fin:
                  fout.write(line.replace('set system host-name EX4300', 'hostname "EX4300"'))
                  fout.write(line.replace('set interfaces ge-0/0/0 unit 0 family inet address', 'ip address'))

Please let me know where I went wrong or if there is a better way of approaching this. I am using Visual Studio Code.

Only use 1 fout.write(), call the replace function al often as you want.

with open("SanitizedFinal_E4300.txt", "rt") as fin:
    with open("output6.txt", "wt") as fout:
        for line in fin:
            line = line.replace('set system host-name EX4300', 'hostname "EX4300"')
            line = line.replace('set interfaces ge-0/0/0 unit 0 family inet address', 'ip address')
            fout.write(line)
