Question

我的问题是，如果我使用两个函数，则此代码不接受两个输入参数。

我也尝试从第二个函数中插入和删除click命令和click选项，但是我总是得到主应用程序正在询问其他参数（需要给出2）或代码未执行的信息第二个功能。（“ add_new_column”）

我在做什么错了？

import pandas as pd

@click.command()
@click.option('--infile', prompt='Your input TSV filename', help='Write your tab separated value filename.')
@click.option('--out', prompt='Your output CSV filename', help='Write your new comma separated value filename.')
def convert_tsv_to_csv(infile, out):
    """Converting a Tab Separated Value into a Comma Separated Value for given files in cli arguments"""
    df = pd.read_csv(infile, delimiter='\t')
    df.to_csv(out, sep=',')

# @click.command()
# @click.option('--out', prompt='Your output CSV filename', help='Write your new comma separated value filename.')
# def add_new_column(out):
#     """Adding a new column named  "price_edited"   """
#     df = pd.read_csv(out, delimiter=',')
#     # this line creates a new cloned column from price column, which is a Pandas series.
#     # we then add the series to the dataframe, which holds our parsed CSV file
#     df['price_edited'] = df['price']
#     # save the dataframe to CSV
#     df.to_csv(out, sep=',')


if __name__ == '__main__':
    convert_tsv_to_csv()
    #add_new_column()```

第二次尝试：

import click
import pandas as pd


@click.command()
@click.option('--infile', prompt='Your input TSV filename', help='Write your tab separated value filename.')
@click.option('--out', prompt='Your output CSV filename', help='Write your new comma separated value filename.')
def convert_tsv_to_csv(infile, out):
    """Converting a Tab Separated Value into a Comma Separated Value for given files in cli arguments"""
    df = pd.read_csv(infile, delimiter='\t')
    df.to_csv(out, sep=',')


def add_new_column():
    """Adding a new column named  "price_edited"   """
    df = pd.read_csv(out, delimiter=',')
    # this line creates a new cloned column from price column, which is a Pandas series.
    # we then add the series to the dataframe, which holds our parsed CSV file
    df['price_edited'] = df['price']
    # save the dataframe to CSV
    df.to_csv(out, sep=',')


if __name__ == '__main__':
    convert_tsv_to_csv()
    add_new_column()

代码只能使用一个功能，而不能使用两个功能
