Python格式化输出的两种方式例子

将输出格式化为以下格式：

　　At t = 0.6s, a ball with
　　initial velocity v0 = 5.000E+00 m/s
　　is located at the height 1.23 m.

1 # coding=utf-8
2 v0 =5.0
3 g = 9.81
4 t = float(input())
5 y = v0*t-0.5*g*t**2
6 print (‘At t = {0:.1f} s, a ball with\ninitial velocity v0 = {1:.3E} m/s\nis located at the height {2:.2f} m.‘ .format(t, v0, y))  #第一种
7 print (‘At t = %.1f s, a ball with\ninitial velocity v0 = %.3E m/s\nis located at the height %.2f m.‘ % (t, v0, y))  #第二种

第二种方法语法 print fmt_str % (conc_val_list)

其中，fmt_str 是一个字符串，里面提供与 conc_val_list 数目相匹配的占位符。占位符意义如下表所示。
