To format numbers with commas in Python, you can use f-strings, which were introduced in Python 3.6. Simply embed the number within curly braces and use a colon followed by a comma, like this:formatted_number = f"{number:,}". This will format the number with commas as thousand separator...
在上述示例中,首先使用"{:,}".format(number)格式化数字,然后使用replace方法将默认的逗号替换为单引号,从而实现自定义的千位分隔符。 批量格式化数字 如果需要批量格式化多个数字,可以将它们放在一个列表中,并使用循环来逐个格式化。 以下是一个示例: # 要格式化的数字列表 numbers = [1000, 10000, 100000, 1000000...
