Python's range () function, for-in loop, and while loop

Range () function and for-in loop

function Prototypes : Range (start, end, scan):

parameter meaning : Start: Count starts from start. The default is starting from 0. For example, range (5) is equivalent to range (0, 5);

End: The technology ends with end, but does not include end . For example: Range (0, 5) is [0, 1, 2, 3, 4] No 5

Scan: The distance between each hop is 1 by default. Example: Range (0, 5) is equivalent to range (0, 5, 1)

code example:

1  forNinchRange (3):2     Print(n)3     4 Print("-----------------------")5 6  forNinchRange (2, 4):7     Print(n)8     9 Print("-----------------------")Ten  One  forNinchRange (2, 8, 2): A     Print(n)

Output:

0

While loop :

1 m = 02 while M < 3:3     print (m) 4     M + = 1

Results:
