Tips in IPython:

edit _i	edit the last input.
edit _	edit the last output.
load file	load file.
()	tuple
[]	list

Code Examples:

def printTD(tuples,dicts):
	"""it receives two args,  tuples, dicts."""
	for i in range(len(tuples)):
		print("tuples[" + str(i) + "] = " + str(tuples[i]), end = ',');
	keys = sorted(dicts.keys(), key = lambda x:len(x));
	for j in keys:
		print("dicts[" + str(j) + "] = " + str(dicts[j]), end = ',');

def foo(arg0,  *tuples,  **dicts):
	"""This is foo function, it receives any number of args."""
	print("foo.__doc__ = " + foo.__doc__);
	print("foo(arg0:"+str( arg0), end = ',');
	printTD(tuples, dicts);
	print(")");
	bar( *tuples,  ** dicts);

def bar(arg0, arg1,  *tuples,  **dicts):
	"""This is bar function"""
	print("bar.__doc__ = " + bar.__doc__);
	print("bar(arg0:" + str(arg0) + ", arg1:" + str(arg1), end = ',');
	printTD(tuples, dicts);
	print(")");

foo("a", "1", 2, "3", mykey1 = 123, adfadfK = 123145, afadf = "afdadf");

Output:

foo.__doc__  =  This is foo function,  it receives any number of args.
foo(arg0:a, tuples[0]  =  1, tuples[1]  =  2, tuples[2]  =  3, dicts[afadf]  =  afdadf, dicts[mykey1]  =  123, dicts[adfadfK]  =  123145, )
bar.__doc__  =  This is bar function
bar(arg0:1, arg1:2, tuples[0]  =  3, dicts[afadf]  =  afdadf, dicts[mykey1]  =  123, dicts[adfadfK]  =  123145, )
