Top Python tricks for efficient programming Strings Trick 6: Reversing the string a=”python” print(“Reverse is”, a[::-1]) Output: Reverse is nohtyp Trick 7: Splitting the string a="Python is the language of the future" b=a.split() print(b) Output: [‘Python’, ‘is’, ‘the’, ‘language’, ‘of’, 'the’, ‘future’] Trick 8: Printing out multiple values of strings print(“on”*3+’ ‘+”off”*2) Output: ononon offoff Trick 9: Creating a single string a = [“I”, “am”, “not”, “available”] print(“ “.join(a)) Output: I am not available Trick 10: Checking if two words are anagrams from collections import Counter def is_anagram(str1, str2): return Counter(str1) == Counter(str2) print(is_anagram(‘taste’, ‘state)) print(is_anagram(‘beach’, ‘peach’)) Output: True False

>>> s = 'mybacon'
>>> s[2:5]
'bac'
>>> s[0:2]
'my'

```python >>> s = 'mybacon' >>> s[:2] 'my' >>> s[2:] 'bacon' >>> s[:2] + s[2:] 'mybacon' >>> s[:] 'mybacon'

python >>> s = 'mybacon' >>> s[-5:-1] 'baco' >>> s[2:6] 'baco'`
