python - Wrong arguments on random.uniform() -

python - Wrong arguments on random.uniform() -

help me, because cant find fault code following:

def getrandomposition(self): """ homecoming random position within room. returns: position object. """ homecoming position(random.uniform(0,self.width),random.uniform(0,self.height))

debugger output:

room.getrandomposition() traceback (most recent phone call last): file "<stdin>", line 1, in <module> file "ps2a.py", line 145, in getrandomposition homecoming position(random.uniform(0,self.width),random.uniform(0,self.height)) typeerror: random() takes no arguments (2 given)

ps:position initializer of form position(x,y) ideas? random.uniform takes 2 arguments documentation

the actual debugger output (pdb):

>>> room=ps2a.rectangularroom( ... 3,3) >>> room.getrandomposition() traceback (most recent phone call last): file "<stdin>", line 1, in <module> file "ps2a.py", line 145, in getrandomposition typeerror: random() takes no arguments (2 given) >>> random.random() traceback (most recent phone call last): file "<stdin>", line 1, in <module> nameerror: name 'random' not defined >>> import random >>> random.uniform(1,3) 2.5039752079488458 >>> room.getrandomposition() traceback (most recent phone call last): file "<stdin>", line 1, in <module> file "ps2a.py", line 145, in getrandomposition homecoming position(random.uniform(0,self.width),random.uniform(0,self.height)) typeerror: random() takes no arguments (2 given) >>> import pdb >>> pdb.run("room.getrandomposition()") > <string>(1)<module>() (pdb) s --call-- > /home/kostas/pythonprojects/l4p5/problemset2/ps2a.py(139)getrandomposition () -> def getrandomposition(self): (pdb) s > /home/kostas/pythonprojects/l4p5/problemset2/ps2a.py(145)getrandomposition() -> homecoming position(random.uniform(0,self.width),random.uniform(0,self.height)) (pdb) p self.width 3 (pdb) p self.height 3 (pdb) s typeerror: 'random() takes no arguments (2 given)' > /home/kostas/pythonprojects/l4p5/problemset2/ps2a.py(145)getrandomposition() -> homecoming position(random.uniform(0,self.width),random.uniform(0,self.height)) (pdb)

the position class, asked:
