f-string (Python 3.6+) str.format()方法 字符串旧式格式化(%) 我们将分别使用这些方法来对齐输出。 1. 使用 f-string numbers=[1.1,2.22,3.333,4.4444]fornuminnumbers:# 使用 f-string 格式化输出,宽度为 8,小数点后两位print(f"{num:8.2f}")# {num:8.2f}表示总宽度8个字符,小数点后保留2位 1. ...
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...
(3). 浮点型(floating point values)浮点型构成由整数部分和小数部分构成 (4). 复数(complex numbers)复数由实数和虚数部分构成 可以使用 a+bj,或 compler(a,b) 表示,其中 a,b部分都是浮点型 注: 长整型的取值范围: python2.7版本中长整型的取值范围为-263-1次方至263次方 python3中没有long类型,使用int...

Python的字符串格式化有两种方式:百分号方式、format方式 百分号的方式相对来说比较老,而format方式则是比较先进的方式,企图替换古老的方式,目前两者并存。[PEP-3101] This PEP proposes a new system for built-in string formatting operations, intended as a replacement for the existing '%' string formatting ope...
echo $myFormattedNumber; // Will print 4 567.38 Note again that the formatted number has been rounded to the required number of decimal places. Conclusion It’s important to be consistent in what format you store numbers. If they are not consistent and formats are mixed, your data will beco...
