(6)%f or%f converted to floating-point numbers, you can add x.y x in front of F to represent the total number of digits, and Y for the right of the decimal point

2. Script instance

User input content, printed on the screen, such as

#!/usr/bin/env python

width = 48
Content = []

While True:
line = Raw_input ("Enter line (. To quit) > ")
if line = = ".":
Break
Content.append (line)

Print "+%s+"% ("*" * width)
For line in content:
Sp_wid, extra = Divmod (Width-len (line)), 2)
Print "+%s%s%s+"% (' * sp_wid, line, ' * (Sp_wid + extra))
Print "+%s+"% ("*" * width)

Actually the string comes with the center function, above just to consolidate the knowledge points
