Python学习

在业余时间学习一下跨平台代码python。

下面是http://courses.ischool.berkeley.edu/i155/su13/schedule.htm下的例题代码。留作未来参考语法。

1 #hw1_1.py
2 x=input("Input the number of gallons of gasoline:")
3 print "Equivalent number of liters:",x*3.7854
4 print "Number of barrels of oil required to produce it:",x/19.5
5 print "Price in US dollars:$",x*3.56,
 1 #hw1_2.py
 2 import sys
 3 name=raw_input("Enter your name:")
 4 n=len(name)
 5 print name[n-1].upper(),
 6 #No space between the output letter
 7 sys.stdout.softspace=0 
 8 i=n-2
 9 while i>=0:
10     print name[i].lower(),
11     sys.stdout.softspace=0
12     i=i-1
13

 

1 #hw1_3.py
2 n=input("Enter a size:")
3 for j in range(0,n):
4     for i in range(-n+1,n):
5         if abs(i)<=j :
6             print j-abs(i)+1,
7         else: 
8             print ' ',
9     print ""
#hw1_4.py
n=input("Enter a size:")
for i in range(0,n):
    for j in range(0,n):
        if (i+j)%2==0:
            print "X",
        else:
            print " ",
    print ""
