問題描述
首先，我嘗試過這篇文章(以及其他):Python 中的貨幣格式.它對我的變量沒有影響.我最好的猜測是因為我使用的是 Python 3，而那是 Python 2 的代碼.(除非我忽略了某些東西，因為我是 Python 新手).
First of all, I have tried this post (among others): Currency formatting in Python. It has no affect on my variable. My best guess is that it is because I am using Python 3 and that was code for Python 2. (Unless I overlooked something, because I am new to Python).
我想將浮點數(shù)(例如 1234.5)轉(zhuǎn)換為字符串，例如$1,234.50".我該怎么做呢?
為了以防萬一，這是我編譯的代碼，但不影響我的變量:
And just in case, here is my code which compiled, but did not affect my variable:
money = float(1234.5)
locale.setlocale(locale.LC_ALL, '')
locale.currency(money, grouping=True)
同樣失敗:
money = float(1234.5)
print(money) #output is 1234.5
'${:,.2f}'.format(money)
print(money) #output is 1234.5
推薦答案
在 Python 3.x 和 2.7 中，您可以簡單地這樣做:
In Python 3.x and 2.7, you can simply do this:
>>> '${:,.2f}'.format(1234.5)
'$1,234.50'
:, 添加逗號作為千位分隔符，.2f 將字符串限制為小數(shù)點后兩位(或添加足夠的零以達到小數(shù)點后兩位，視情況而定)在最后.
The :, adds a comma as a thousands separator, and the .2f limits the string to two decimal places (or adds enough zeroes to get to 2 decimal places, as the case may be) at the end.
