如何将十亿或百万缩写的字符串转换为列表中的整数 [英] How to convert strings with billion or million abbreviation into integers in a list

问题描述

我很少有字符串项目，这些字符串项目是列表中具有十亿或百万缩写的数字:

i have few string items which are the numbers with billion or million abbreviation in a list:

list = ["150M", "360M", "2.6B", "3.7B"]

我想使用一种语法，可以将这些字符串项转换为以千为单位的整数(例如150M> 150,000，3.7B> 3,700,000)，谢谢

I would like to use a syntax that could convert those string items into integers counted in thousands (e.g 150M > 150,000, 3.7B> 3,700,000 ), thanks

推荐答案

您可以将列表理解与dict映射一起使用:

You can use list comprehension with a dict mapping:

l = ["150M", "360M", "2.6B", "3.7B"]
m = {'K': 3, 'M': 6, 'B': 9, 'T': 12}
print([int(float(i[:-1]) * 10 ** m[i[-1]] / 1000) for i in l])

这将输出:

[150000, 360000, 2600000, 3700000]
