Python base variable assignment, if statement

1. Assigning values to variables

Letters are quoted as strings, not labeled as variable names.

" Jbzhang "  = nameprint="jbz"print(name2)

Memory Reclamation: The memory space created, when there is no variable pointing, the memory space will be emptied or deleted directly.

Like what:
1. Delete directly
Age=21
Del age
2. Cancel the point
Age=22
Age=23

2.if Statement Implementation guess age

Age_of_princal= + = Int (input (">>:"))if guess_age = = age_of_princal:     Print ("yes,you got it. " Else:    print("no,it ' s wrong . ")

3. Multi-Branch If statement

score= Int (Input ("Score:"))ifScore > 90:    Print("A")elifScore > 80:    Print("B")elifScore > 70:    Print("C")elifScore > 50:    Print("D")Else:    Print("Roll")
