\t didn't appear in the for loop-CodePudding

I'm practicing format fuction and when I use this code with \t in it, the first 9 output did not have any big space `

import random
lst = [random.randint(1,100) for i in range(51)]
for index, val in enumerate(lst):
    print(f'{index=}\t{val=}')

It works with \n but not \t, I don't know why. Can anyone explain it?

CodePudding user response：

It's just the terminal following tab convention(4 spaces into consideration). So add spaces before and after \t.

CodePudding user response：

All results has \t

Run your code with python yourcode.py | cat -T

This is the results. ^I is the tab.

$ python yourcode.py | cat -T
index=0^Ival=14
index=1^Ival=46
index=2^Ival=87
index=3^Ival=83
index=4^Ival=28
index=5^Ival=77
index=6^Ival=34
index=7^Ival=66
index=8^Ival=64
index=9^Ival=80
index=10^Ival=28
index=11^Ival=21
index=12^Ival=64
index=13^Ival=79
index=14^Ival=92
index=15^Ival=67
index=16^Ival=69
index=17^Ival=50

Man page of cat says

  -T, --show-tabs
         display TAB characters as ^I

You may change the length of TAB. Check this article
