Python 入门

感觉Python 有点像shell 有点像java 有点像matlab，值得一学!!可是呢，学不会呢怎么办，只会简单的语法而已,复杂的就不知如何下手了``` #intlist = [];

#print 'Input a digit'
#n = int(raw_input());
#for i in range(1,n):
#    intlist.append(i)
#print intlist

age = 20
name = 'xierunquan'

#print '%s is %d' %(name,age)
ab = {
        'x1':'apple',
        'x2':'orange',
        'x3':'pear',
        #会覆盖的
        'x1':'yy'
     }

print '%s' %ab['x1']

ab['x2'] = 'pig'
del ab['x3']

for x,y in ab.items():
    print '%s : %s' %(x,y)

if('x3') in ab:
    print 'yes'
else:
    print 'no'
    
def f():
    '''just test

    ==========='''
print f.__doc__

if __name__ == '__main__':
    print 'by itself'
else:
    print 'by others'
