# 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

Returns all the elements of a list except the last one

Example:

```def tips_initial(lst):
return lst[0:-1]

print(tips_initial([1, 2, 3, 4]))
```

Output:

```[1, 2, 3]
