Scientific notation. Same as 'e' except it uses an upper case 'E' as the separator character. 'f' Fixed-point notation. For a given precision p, formats the number as a decimal number with exactly p digits following the decimal point. With no precision given, uses a precision of 6 dig...

The format specifier {:.2f} rounds the number to 2 decimal places. The function is similar to the string format method but called as a standalone function. It's useful when you need to format values dynamically. Number FormattingThe format function provides extensive options for number ...
数字型(Number) 数字型数据类型包括整型(int)、浮点型(float)、布尔型(bool)和复数型(complex)等。其中,整型用于表示整数,浮点型用于表示浮点数或科学计算中的实数,布尔型用于表示 True 和 False 两个值,复数型用于表示实部和虚部都为浮点数的复数。

When there are a lot of leading zeros as in your example, the scientific notation might be easier to read. In order to print a specific number of digits after a decimal point, you can specify a format string with print: print 'Number is: %.8f' % (float(a[0]/a[1])) Or you ...
