What will be the output of the following programming code?

str = "My Python Programming"
print (str[-5:-1])
print (str[1:5])
print (str[:-4])
print (str[0:])
print (str[:13-4])
print (str[:3])

mmin
y Py
My Python Program
My Python Programming
My Python
My 

Working

1. str[-5:-1] extracts the substring from the 5th last character up to, but not including, the last character: "mmin".
2. str[1:5] extracts the substring from index 1 to 4: "y Py".
3. str[:-4] extracts the substring from the beginning up to, but not including, the last 4 characters.
4. str[0:] extracts the substring from index 0 to the end.
5. str[:13-4] is equivalent to str[:9], which extracts the substring from the beginning up to, but not including, index 9: "My Python".
6. str[:3] extracts the substring from the beginning up to, but not including, index 3: "My ".
