Python: AttributeError: 'str' object has no attribute 'readlines'
<p>I am trying to copy text from <code>mobileBuildSettings</code> and use it to replace text from <code>abproject</code>. I am getting the following error and I don't understand it.</p>

<pre><code>AttributeError: 'str' object has no attribute 'readlines'
</code></pre>

<p>Below is my code:</p>

<pre><code>with open("C:/abproject.build", "r+") as script, open ("C:/tempfile.build","w+") as newscript:
abproject = ("C:/abproject.build")
for line in abproject.readlines():
    if line == "@AppIdentifier@" :
        newabproject.write('"' + "AppIdentifier : " + '"' + appIdentifier.get() + '"' + "\n")
    else:
        newabproject.write(line)
abproject.close()
newabproject.close()
os.remove("abproject.txt")
os.remove("tempfile.buil","abproject.txt")
</code></pre>
