Inputs:
filename - name of CSV file
separator - character that separates fields
quote - character used to optionally quote fields
Ouput:
A list of strings corresponding to the field names in
the given CSV file.

这是我的 csv 文件 Table1.csv = Field1,Field2,Field3,Field4 中的数据
预期输出 = ['Field1', 'Field2', 'Field3', 'Field4']
运行代码后=TypeError，引用必须是整数
quote - 用于可选地引用字段的字符
是的，但您将其传递给quoting此处的参数：
reader = csv.reader(csv_file, delimiter=separator, quoting=quote)
然而quoting 期望一个整数。要指定引号字符，请使用quotechar参数。
