Python: Index number of all lower case letters in a given string
Python Basic - 1: Exercise-129 with Solution
Write a Python program to get the index number of all lower case letters in a given string.
Sample Solution-1:
Python Code:
def test(text):
return [x for x in range(len(text)) if text[x].islower()]
text = "Python";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
text = "JavaScript";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
text = "PHP";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
Sample Output:
Original string: Python Indices of all lower case letters of the said string: [1, 2, 3, 4, 5] Original string: JavaScript Indices of all lower case letters of the said string: [1, 2, 3, 5, 6, 7, 8, 9] Original string: PHP Indices of all lower case letters of the said string: []

Sample Solution-2:
Python Code:
def test(text):
return [index for index, element in enumerate(text) if element.islower()]
text = "Python";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
text = "JavaScript";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
text = "PHP";
print("Original string:",text)
print("Indices of all lower case letters of the said string:\n",test(text))
Sample Output:
Original string: Python Indices of all lower case letters of the said string: [1, 2, 3, 4, 5] Original string: JavaScript Indices of all lower case letters of the said string: [1, 2, 3, 5, 6, 7, 8, 9] Original string: PHP Indices of all lower case letters of the said string: []

What is the difference between Python's list methods append and extend?
append: Appends object at the end.
x = [1, 2, 3] x.append([4, 5]) print (x)
Output:
[1, 2, 3, [4, 5]]
extend: Extends list by appending elements from the iterable.
x = [1, 2, 3] x.extend([4, 5]) print (x)
Output:
[1, 2, 3, 4, 5]
