This is to use Python 

I create a list withe the building names

'Richard Weeks Hall’, ’Busch Student Center’, ‘Environmental & Natural Resource Sciences Building’

How would I code for this?

• If the name contains ‘Hall’, remove the word ‘Hall’ from the name. 
• If the name contains ‘Building’, replace it with ‘Bldg’. 

Expert Solution
Step 1

Following is the python program:
Approach:

  • create a list to store the names of the building.
  • using for loop print the names of the list before modification.
  • use the replace() function to replace the substring Hall with null and replace the substring Building with Bldg.
Step 2

Code:

# creating a list having building names.
strings = ["Richard Weeks Hall", "Busch Student Center", "Environmental & Natural Resource Sciences Building"]
# Display all string elements in list.
for st in strings:
    print(st)
# Replace substring in list of strings 
res = [sub.replace('Hall', '').replace('Building', 'Bldg') for sub in strings]
# print result 
print("\nThe list after substring replacement : ") 
for st in res:
    print(st)
