Form generating error when using GET request

My HTML code:

<form method="GET" action="/">
    <input type="text" name="query">
    <button type="submit">Search</button>
</form>

My python code:

@app.route('/alumni',methods=['POST','GET'])
def alumni():

    if request.method == 'GET':
        query = request.form['query']

        return render_template('alumni.html',query=query)

When I'm loading page it is giving error, I know that this error is because when we are loading page for first time we will have no query, if I use method=POST to pass queries then my problem will be solved but POST will not show the query, I want query to be shown, what to do?

Since request.form is a dictionary-like object, you can use the .get method to provide a default value:

query = request.form.get('query', '')

This will use the query argument when available, or an empty string when it is not.

Update: Since you are using the GET method you should probably be using args:

query = request.args.get('query', '')
