This Shorthand If lesson is for a beginner. Read the short notes, run each example, then change one name or number and run it again.
A single action can sit on the same line as if. Keep that line short enough to read in one glance.
As soon as you need a second statement, move the body onto indented lines.
Example 1: Start here
The colon is still required.
score = 82 # a whole number
if score >= 70: print("pass") # run the indented lines only when this is true
Example 2: One-line if
A single action can sit on the same line as the if.
score = 82 # a whole number
if score >= 80: print("Pass") # run the indented lines only when this is true
Example 3: Choose a value
This form always produces a value, so it fits inside print.
score = 70 # a whole number
print("Pass" if score >= 80 else "Try again") # a comparison is True or False
Example 4: Keep the long form when it grows
Use the indented form as soon as you need more than one line.
score = 82 # a whole number
if score >= 80: # run the indented lines only when this is true
print("Pass")
print(score)
The colon is still required.
