# Python: Check whether all items of a list is equal to a given string

## Python List: Exercise - 57 with Solution

Write a Python program to check if all items in a given list of strings are equal to a given string. Sample Solution-1:

Python Code:

``````color1 = ["green", "orange", "black", "white"]
color2 = ["green", "green", "green", "green"]

print(all(c == 'blue' for c in color1))
print(all(c == 'green' for c in color2))
```
```

Sample Output:

```False
True
```

Sample Solution-2:

Checks if all elements in a list are equal:

Use set() to eliminate duplicate elements and then use len() to check if length is 1.

Python Code:

``````def all_equal(nums):
return len(set(nums)) == 1
print(all_equal([1, 2, 3, 4, 5, 6]))
print(all_equal([4, 4, 4, 4, 4]))
```
```

Sample Output:

```False
True
```

## Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

```def tips_check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))
```

Output:

```True
```
