python起步

# Fig. D.1: test.py
# Simple program to demonstrate debugging.

# prompt user for input
integer = raw_input( "Enter an integer:/n" ) 
integer = int( integer )

if integer < 0:
  print "%d is less than zero" % integer
else:
  print "%d is not less than zero" % integer

python其实很好懂，不过要学到极致的话，就得下苦功夫。

 

raw_input函数是读取用户的输入的

int函数是将integer参数转换为整数
