Python: Remove the first and last elements from a given string
Python Basic - 1: Exercise-123 with Solution
Write a Python program to remove the first and last elements from a given string.
Sample Solution-1:
Python Code:
def test(str):
return str if len(str) < 3 else str[1:-1]
str = "PHP"
print("Original string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
str = "Python"
print("\nOriginal string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
str = "JavaScript"
print("\nOriginal string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
Sample Output:
Original string: PHP Removing the first and last elements from the said string: H Original string: Python Removing the first and last elements from the said string: ytho Original string: JavaScript Removing the first and last elements from the said string: avaScrip
Flowchart:

Sample Solution-2:
Python Code:
def test(str):
return str[1:-1] if len(str) > 2 else str
str = "PHP"
print("Original string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
str = "Python"
print("\nOriginal string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
str = "JavaScript"
print("\nOriginal string: ",str)
print("Removing the first and last elements from the said string: ",test(str))
Sample Output:
Original string: PHP Removing the first and last elements from the said string: H Original string: Python Removing the first and last elements from the said string: ytho Original string: JavaScript Removing the first and last elements from the said string: avaScrip

Python: Tips of the Day
Iterating over dictionaries using 'for' loops:
I am a bit puzzled by the following code: d = {'x': 1, 'y': 2, 'z': 3} for key in d: print key, 'corresponds to', d[key] What I don't understand is the key portion. How does Python recognize ...
key is just a variable name.
for key in d:
For Python 3.x:
for key, value in d.items():
For Python 2.x:
for key, value in d.iteritems():
To test for yourself, change the word key to poop.
In Python 3.x, iteritems() was replaced with simply items(), which returns a set-like view backed by the dict, like iteritems() but even better. This is also available in 2.7 as viewitems().
The operation items() will work for both 2 and 3, but in 2 it will return a list of the dictionary's (key, value) pairs, which will not reflect changes to the dict that happen after the items() call. If you want the 2.x behavior in 3.x, you can call list(d.items()).
