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)[0] == str(lst[0])[0] 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))
