Question

Write the output of the following code and explain the output. (10 marks)

str='MIS 525'

str[4]='-'

print(str)

Error Message:

Traceback (most recent call last): File "number6.py", line 2, in <module> str[4]='-'

What is the reason why this code does not run? How can you fix it?

Answer 1

As strings are immutable in python we cannot change the elements in the string by indexing

WE can correct the error by joining lists by splicing

str='MIS 525'
# str[4]='-'
str=str[:3]+'-'+str[4:]
print(str)

The output is given below
