Print all variables in a class? - Python
Question
I'm making a program that can access data stored inside a class. So for example I have this class:
#!/usr/bin/env python
import shelve
cur_dir = '.'
class Person:
def __init__(self, name, score, age=None, yrclass=10):
self.name = name
self.firstname = name.split()[0]
try:
self.lastname = name.split()[1]
except:
self.lastname = None
self.score = score
self.age = age
self.yrclass = yrclass
def yrup(self):
self.age += 1
self.yrclass += 1
if __name__ == "__main__":
db = shelve.open('people.dat')
db['han'] = Person('Han Solo', 100, 37)
db['luke'] = Person('Luke Skywalker', 83, 26)
db['chewbacca'] = Person('Chewbacca', 100, 90901)
So using this I can call out a single variable like:
print db['luke'].name
But if I wanted to print all variables, I'm a little lost.
If I run:
f = db['han']
dir(f)
I get:
['__doc__', '__init__', '__module__', 'age', 'firstname', 'lastname', 'name', 'score', 'yrclass', 'yrup']
But I want to be able to print the actual data of those.
How can I do this?
Thanks in advance!
Solution
print db['han'].__dict__
OTHER TIPS
Rather than using magic methods , Vars could be more preferable.
print(vars(db['han']))
Just try beeprint
after pp(db['han'])
, it will print this:
instance(Person):
age: 37
firstname: 'Han',
lastname: 'Solo',
name: 'Han Solo',
score: 100,
yrclass: 10
no methods, no private properties.
print(vars(objectName))
Output: {'m_var1': 'val1', 'm_var2': 'val2'}
This will print all the class variables with values initialised.
