python flask视图返回报错：TypeError: Object of type function is not JSON serializable

原因 数组名不能有_

team_list = [
    {"id": 1, "name": "a"},
    {"id": 2, "name": "b"},
    {"id": 3, "name": "c"},
    {"id": 4, "name": "d"},
]
@app.route("/team/list")
def team_list():
    return jsonify(team_list)

报错

改成

teamlist = [
    {"id": 1, "name": "a"},
    {"id": 2, "name": "b"},
    {"id": 3, "name": "c"},
    {"id": 4, "name": "d"},
]
@app.route("/team/list")
def team_list():
    return jsonify(teamlist)

成功
