python - 如何迭代多个函数参数？

Question

我尝试使用 locals() 或 *args 来迭代多个函数参数。但是，我将函数参数定义为数据框中的列。如何编辑以下内容以使 float_format 函数迭代可变数量的参数？

#! /usr/bin/env python3

import pandas as pd

def float_format(a, b, c, d, e, f): #Change to single *args function argument?
        for x in range(len(data[a])):
                data[a][x] = data[a][x].replace(' Mbps', '')
        for x in range(len(data[b])):
                data[b][x] = data[b][x].replace(' Mbps', '')
        for x in range(len(data[c])):
                data[c][x] = data[c][x].replace(' Mbps', '')                
        for x in range(len(data[d])):
                data[d][x] = data[d][x].replace(' Mbps', '')
        for x in range(len(data[e])):
                data[e][x] = data[e][x].replace(' Mbps', '')
        for x in range(len(data[f])):
                data[f][x] = data[f][x].replace(' Mbps', '')

file = r'Original_File.xls'
data = pd.read_excel(file, header=[2])

float_format('Average Receive bps',
               'Peak Receive bps',
               'Received Bandwidth',
               'Average Transmit bps',
               'Peak Transmit bps',
               'Transmit Bandwidth')

data.to_excel('results.xlsx', 'w+')

所以如果我尝试

def float_format(*iterate):
        for arg in iterate:
            for x in range(len(data[iterate])):
                    data[iterate][x] = data[iterate][x].replace(' Mbps', '')

我在函数运行的过程中遇到了回溯错误。

示例 df

下面这个怎么样？

def test(*argv):
    for arg in argv:
            print(arg)

test('hello', 'world')
# hello
# world
