Python: Check whether a given string has a capital letter, a lower case letter, a number and specified length using lambda

Python Lambda: Exercise-33 with Solution

Write a Python program to check whether a given string contains a capital letter, a lower case letter, a number and a minimum length using lambda.

Sample Solution:

Python Code :

def check_string(str1):
    messg = [
    lambda str1: any(x.isupper() for x in str1) or 'String must have 1 upper case character.',
    lambda str1: any(x.islower() for x in str1) or 'String must have 1 lower case character.',
    lambda str1: any(x.isdigit() for x in str1) or 'String must have 1 number.',
    lambda str1: len(str1) >= 7                 or 'String length should be atleast 8.',]
    result = [x for x in [i(str1) for i in messg] if x != True]
    if not result:
        result.append('Valid string.')
    return result    
s = input("Input the string: ")
print(check_string(s))

Sample Output:

Input the string:  W3resource
['Valid string.']

Python: Tips of the Day

Inverts a dictionary with unique hashable values:

Example:

def tips_invert_dictionary(obj):
  return { value: key for key, value in obj.items() }
ages = {
  "Owen": 29,
  "Eddie": 15,
  "Jhon": 22,
}
print(tips_invert_dictionary(ages))

Output:

{29: 'Owen', 15: 'Eddie', 22: 'Jhon'}
