    $(document).ready(function(){

        if ($bar.width()>=400) {
            clearInterval(progress);
            $('.progress-bar').removeClass('active');
        } else {

    @-moz-keyframes animateBar {

打印出来：

print('this is £{0:>10.2f}'.format(3.44))

即。将this is £ 3.44与金额分开。有没有办法在正确的位置打印带有货币符号的打印间隔列，在金额旁边？ E.g。

£

我尝试了this is £3.44，但得到了：

print('this is {0:£>10.2f}'.format(3.44))

Answer 1

您需要分两步执行此操作，一个用于货币符号和小数位，另一个用于右对齐空格：

>>> 'this is {:>10}'.format('£{:.2f}'.format(3.44))
'this is      £3.44'

如果您想要逗号分隔数千，您还可以在格式规范中包含,：

>>> 'this is {:>10}'.format('£{:,.2f}'.format(1003.44))
'this is  £1,003.44'

Answer 2

你使用右对齐{：＆gt; 10}，如果你想左对齐，试试这个：

In[21]: print('this is £{0:<10.2f}'.format(3.44))
this is £3.44

带对齐的字符串格式货币
