I am using the following function from https://stackoverflow.com/questions/32500167/how-to-show-diff-of-two-string-sequences-in-colors to find the difference in color between two strings. The function is:
from colorama import *
import numpy as np
inv_WHITE = Fore.WHITE[::-1]
inv_RED = Fore.RED[::-1]
inv_GREEN = Fore.GREEN[::-1]
def edDistDp(y, x):
res = inv_WHITE
D = np.zeros((len(x) + 1, len(y) + 1), dtype=int)
D[0, 1:] = range(1, len(y) + 1)
D[1:, 0] = range(1, len(x) + 1)
for i in range(1, len(x) + 1):
for j in range(1, len(y) + 1):
delt = 1 if x[i - 1] != y[j - 1] else 0
D[i, j] = min(D[i - 1, j - 1] + delt, D[i - 1, j] + 1, D[i, j - 1] + 1)
# print D
# iterate the matrix's values from back to forward
i = len(x)
j = len(y)
while i > 0 and j > 0:
diagonal = D[i - 1, j - 1]
upper = D[i, j - 1]
left = D[i - 1, j]
# check back direction
direction = (
"\\"
if diagonal <= upper and diagonal <= left
else "<-"
if left < diagonal and left <= upper
else "^"
)
# print "(",i,j,")",diagonal, upper, left, direction
i = i - 1 if direction == "<-" or direction == "\\" else i
j = j - 1 if direction == "^" or direction == "\\" else j
# Colorize caracters
if direction == "\\":
if D[i + 1, j + 1] == diagonal:
res += x[i] + inv_WHITE
elif D[i + 1, j + 1] > diagonal:
res += y[j] + inv_RED
# res += x[i] + inv_GREEN
else:
# res += x[i] + inv_GREEN
res += y[j] + inv_RED
elif direction == "<-":
res += x[i] + inv_RED
elif direction == "^":
res += y[j] + inv_RED
return res[::-1]
when I write the output of this function using st.write(edDistDp('hat','cat')), I get the following output. m23;1[ehm53;1[eam53;1[etm53;1[e I know that colorama is used to color strings in the terminal. Is there a way to solve this issue and have the difference between (hat) and (cat) which is thw two letters (h,c) highlighted in another color and output in streamlit?
