There are a few syntax errors in the code:

1. "Import" should be replaced with "import"
2. "From flask import requset" should be replaced with "from flask import request"
3. The indentation for the "if student_name:" statement is incorrect, it should be indented one level deeper
4. The return statement is missing a closing parenthesis

import flask import pandas as pd from flask import request

app = flask.Flask(name)

@app.route("/query_grade", methods=["GET", "POST"]) def query_grade(): df = pd.read_excel("学生成绩表.xlsx") grade_data = pd.DataFrame() student_name = request.form.get("student_name", "") if student_name: grade_data = df.query(f"姓名=='{student_name}'") return f"""

查询学生数据
