Today is the 9th day since tooth extraction and implant, gums are still swollen. Feeling unwell due to cold weather. Learned about if, else, elif, and, and the importance of indentation in coding. Created a login system with specific usernames and passwords.

Study Notes

Today, I learned two related statements: if, else, elif, and, and.
elif follows the if statement in the judgment.
and is used when multiple conditions must be met for the statement to be true.
Indentation is crucial!

CODE

print("MY LOGIN SYSTEM")
print("+++++++++++++++")
varname=input("Username > ")
varpasswd=input("Password > ")
if varname=="David" and varpasswd=="toallyNotBald":
  print("Hey David")

  print("Hey Lily")
