# Python: Check if a given value is a method of a user-defined class

## Python module: Exercise-2 with Solution

Write a Python program to check if a given value is a method of a user-defined class. Use types.MethodType()

Sample Solution:

Python Code:

``````import types
class C:
def x():
return 1
def y():
return 1

def b():
return 2

print(isinstance(C().x, types.MethodType))
print(isinstance(C().y, types.MethodType))
print(isinstance(b, types.MethodType))
print(isinstance(max, types.MethodType))
print(isinstance(abs, types.MethodType))
```
```

Sample Output:

```True
True
False
False
False
```

## Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

```def tips_collect_dictionary(obj):
inv_obj = {}
for key, value in obj.items():
inv_obj.setdefault(value, list()).append(key)
return inv_obj
ages = {
"Owen": 25,
"Jhon": 25,
"Pepe": 15,
}
print(tips_collect_dictionary(ages))
```

Output:

```{25: ['Owen', 'Jhon'], 15: ['Pepe']}
```
