Python float警告，删除命令

Question

我是Python新手，

我知道这个价格：1304.20-1500.20-4.10-140.50
如何删除逗号？你知道吗

for open_price in df_open:
    if ',' in open_price:
        open_priceClean = open_price.replace(',', '')
        continue
    prices.append(float(open_priceClean))

我得到这个警告：

TypeError
Traceback (most recent call last) <ipython-input-67-80afd251c13d> in <module>()
     10 #Create the dependent data set 'y' as prices
     11 for open_price in df_open:
---> 12     if ',' in open_price:
     13         open_priceClean = open_price.replace(',', '')
     14         continue

TypeError: argument of type 'float' is not iterable

Answer 1

试试这个：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
df_open = open("test.txt","r")
read_file = df_open.read().splitlines()
print (read_file)

for line in read_file:
    no_comas = (line.replace(",",""))
    print (no_comas)
