# Python: Check if first digit/character in each element in a given list is same or not

## Python List: Exercise - 204 with Solution

Write a Python program to check if the first digit or character of each element in a list is the same.

Sample Solution:

Python Code:

``````def test(lst):
result = all(str(x) == str(lst) for x in lst)
return result
nums = [1234, 122, 1984, 19372, 100]
print("\nOriginal list:")
print(nums)
print("Check if first digit in each element of the said given list is same or not!")
print(test(nums))
nums = [1234, 922, 1984, 19372, 100]
print("\nOriginal list:")
print(nums)
print("Check if first digit in each element of the said given list is same or not!")
print(test(nums))
nums = ['aabc', 'abc', 'ab', 'a']
print("\nOriginal list:")
print(nums)
print("Check if first character in each element of the said given list is same or not!")
print(test(nums))
nums = ['aabc', 'abc', 'ab', 'ha']
print("\nOriginal list:")
print(nums)
print("Check if first character in each element of the said given list is same or not!")
print(test(nums))
```
```

Sample Output:

```Original list:
[1234, 122, 1984, 19372, 100]
Check if first digit in each element of the said given list is same or not!
True

Original list:
[1234, 922, 1984, 19372, 100]
Check if first digit in each element of the said given list is same or not!
False

Original list:
['aabc', 'abc', 'ab', 'a']
Check if first character in each element of the said given list is same or not!
True

Original list:
['aabc', 'abc', 'ab', 'ha']
Check if first character in each element of the said given list is same or not!
False
```

## 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
```
