step1：数据写入csv配置文件

 1 def csv_writer():
 2     '''写入csv文件'''
 3     headers = ["编号", "课程", "讲师"]
 4 
 5     rows = [
 6         (1, "A", "AA"),
 7         (2, "B", "BB"),
 8         (3, "C", "CC")
 9     ]
10     with open("ZGXTest.csv", "w", encoding="GBK", newline="") as f:
11         writer = csv.writer(f)
12         writer.writerow(headers)
13         writer.writerows(rows)

 step2：读取csv文件数据

 1 def csv_reader():
 2     '''读取csv文件'''
 3     with open("ZGXTest.csv", encoding="GBK") as f:
 4         # reader = csv.DictReader(f)
 5         # 读取每一行
 6         reader = csv.reader(f)
 7         # 配置表头
 8         headers = next(reader)
 9         # 打印表头
10         print(headers)
11         # 打印每一行（无表头）
12         for row in reader:
13             print(row)

step3：调用

1 if __name__ == "__main__":
2     csv_writer()
3     csv_reader()
