在 python 3.5 的輸入列表中添加美元符號、逗號和大括號 (Adding dollar signs, commas and curly brackets to input list in python 3.5)

問題描述

在 python 3.5 的輸入列表中添加美元符號、逗號和大括號 (Adding dollar signs, commas and curly brackets to input list in python 3.5)

當我在 python 3.5 中打印代碼時，我想在我的代碼中添加 $、逗號和大括號

list1 = input('enter four numbers')

一旦我得到我打印的值

print ('numbers are: ${:,.2f}',format(list1))

一旦它打印我得到

numbers are: ${:,.2f} 6 7 8 9 

答案應該是這樣的

{$12.95, $1,234.56, $100.00, $20.50}

參考解法

方法 1:

You might want to use something like:

"Numbers are " + ' '.join("${:,.2f}".format(n) for n in list1)

There are basically three operands here:

"Numbers are " +
# Just the simple string tacked on the front

' '.join( ... )
# Joins its contents with a space separator

"${:,.2f}".format(n) for n in list1
# Creates a list of the strings with the requested formatting.

Unroll that backwards to build a list of the properly formatted strings, join them with a space separator, and tack them on to the end of your static string.
