Instead of

i = 0 while i < len(text): j = ord(text[i]) ... ... ... i += 1 

and using text[i] for accessing individual elements (which is NOT a Pythonic way).
Get rid of i and write simply

for c in text: j = ord(c) ... ... ... 

 j = ord(text[i]) k = bin(ord(text[i])) l = hex(ord(text[i])) m = oct(ord(text[i])) 

After performing the first of those commands is ord(text[i]) already in the variable j, isn't it? So why not reuse it in the rest of them:

for c in text: j = ord(c) k = bin(j) l = hex(j) m = oct(j) 

Instead of

print(text[i], " ", j, " ", k, "", l, "", m) 

use the format() method and replacement fields {}:

print("{} {} {} {} {}".format(text[i], j, k, l, m)) 

What about following the PEP 8 -- Style Guide for Python Code?
This style guide is about consistency. Consistency with this style guide is important.

Your code will become

from tkinter.colorchooser import askcolor def text_data(text): texti = [] binary = [] ordv = [] hexadecimal = [] octal = [] i = 0 while i < len(text): j = ord(text[i]) k = bin(ord(text[i])) l = hex(ord(text[i])) m = oct(ord(text[i])) k = k[2:] l = l[2:] m = m[2:] print(text[i], " ", j, " ", k, "", l, "", m) binary.append(k) ordv.append(j) hexadecimal.append(l) texti.append(text[i]) octal.append(m) i += 1 print("\n") print(binary) print("\n") print(ordv) print("\n") print(hexadecimal) print("\n") print(octal) def colorcode(): return askcolor()[1] print(colorcode()) 

Note particularly surrounding your function definitions with 2 blank lines.

(You may check it online: PEP8 online - as your original code, as this one.)
