Stuff about Python

- unimport a module

import sys
import AA.BB    as CC;

del sys.modules["AA.BB"]

- function trace

def flog(format, *params):
    print("mytest: "+format % params)

def myfunction(a, b)
    flog("%s %s", sys._getframe().f_code.co_name, locals())
    pass

- replace '\' with '/':

full_path = os.path.realpath(__file__);
full_path = full_path.replace('\\','/')

Copy and DeepCopy

import copy  

al = [[1],[2],[3]]  
bl = copy.copy(al)  
cl = copy.deepcopy(al)

print "before=>"  
print al  #[[1], [2], [3]]
print bl  #[[1], [2], [3]]
print cl  #[[1], [2], [3]]

al[0][0] = 0  
al[1] = None  
 
print "after=>"  
print al  #[[0], None, [3]]
print bl  #[[0], [2], [3]]
print cl  #[[1], [2], [3]]

#---------------------------------------------
import copy  
al = [1,2,3]  
bl = copy.copy(al)  
cl = copy.deepcopy(al)

print "before=>"  
print al  #[[1], [2], [3]]
print bl  #[[1], [2], [3]]
print cl  #[[1], [2], [3]]

al[0] = 0  
al[1] = None  
 
print "after=>"  
print al  #[0, None, 3]
print bl  #[1, 2, 3]
print cl  #[1, 2, 3]

Send Email

    msg['From']    = me  
    msg['To']      = ";".join(to_list)  
    try:  
        server = smtplib.SMTP('localhost')  
        server.sendmail(me, to_list, msg.as_string())  
        server.close()  
        return True  
    except Exception, e:  
        print str(e)  
        return False  

if __name__ == '__main__':  
    if send_mail(mailto_list,"hello","hello world!"):
        print "good"  
    else:  
        print "bad"
