Consider the statements given below and then choose the correct output from the given options:
myStr = "MISSISSIPPI"
print(myStr[:4] + "#" + myStr[-5:])
myStr = "MISSISSIPPI"
print(myStr[:4] + "#" + myStr[-5:])
Show Hint
MISSI#SIPPI
MISS#SIPPI
MISS#IPPIS
MISSI#IPPIS
The Correct Option is B
Solution and Explanation
myStr[:4]extracts the first 4 characters, which are"MISS".myStr[-5:]extracts the last 5 characters, which are"SIPPI".- These two substrings are concatenated with a
"#"in between, resulting in"MISS#SIPPI".
