### Cheat Sheet by juicyy (Example)

Print (2) – integer
Print (2.5) – floating point
Print (“Hello”) – string
Print (mystr) – variable
Print (mystr­­,”­H­i­”,­­2,1.0) -- commas

mystr = “Hi”
mystr ← name
“Hi” ← value can change

print (int(1.5)) → 1
print (int(“2”)) → 2
print (float(1)) → 1.0 anything to a float
