如何将python中的一个字符旋转90度？

Question

I'm trying to rotate the character | sideways by 90 degrees, think of a longer - and then print it.

would appreciate the help as to how I can do that?

Answer 1

For converting '|' char to 90 degree, we can replace with all chars '|' to '—' chars.

s1 = "Example | text | with | horizontal | string"

def RotateCharacter90(s1):
    s2 = s1.replace( "|", "—")
    return s2

print(RotateCharacter90(s1))

""" OUTPUT: Example — text — with — horizontal — string """

Answer 2

Can you just print an em dash, "—"? In many fonts, an em dash is as long as the font's letters are tall.

Here's some example code that "rotates" the "|"symbol in the console in a complete circle for a loading animation by replacing it with em dashes and forward and backward slashes.

import time
import sys

def loadingAnimation():
    #Run for 10 seconds
    timeToRun = time.time() + 10
    while time.time() < timeToRun:
        wheelAnim = ['|','/','—','\\']
        for frame in wheelAnim:
            sys.stdout.write('\rLoading... %s' % frame)
            #Hold each frame for 0.15 seconds
            time.sleep(0.15)
            sys.stdout.flush()
          
    sys.stdout.write('\rLoading... complete.\n')
  
loadingAnimation()
