Python Basics (3) If_else, for, while, break, and continue

1. If ... else

1 a=62if a>=5:3     print("TheA is bigger than 5")4Else:5     print( " The A is smaller than 5 ")

2. For loop

1 # for I in range: #默认从0开始, stepping is 1 equivalent to C language for (i=0;i<10;i++) 2  for  in Range (1,10,3):# starting from 1, the step is 33     print("Loop:  ", i)

3. While loop

1 count=02 while True:3     print("  You are the wind I am the sand, wrapped around the horizon ... " , Count) 4     Count +=1

4. Break and Continue

1 #Break to completely exit this layer loop2  whileTrue:3     Print("break:123")4      Break5     Print("456")6 7 #continue is used to exit this loop and continue the next cycle8  whileTrue:9     Print("continue:123")Ten     Continue One     Print("456")

5, While+else

# Unlike other languages else, which is usually only the same as if, there is a while ... else statement in Python, and the else function after the while is the
When the while loop executes normally and the middle is not interrupted by a break, the statement after the else is executed
