The ndiff() function of the Python difflib module

Overview:

The ndiff() function of Python difflib module returns a generator object containing differences between two lists of strings.
Each difference is listed in the format <opcode, string>.
When the opcode is '- ' the string is present only in the first string and when it is '+ ' the string is present only in the second string.
If the opcode is ' ' there is no difference between the strings. The opcode '? ' represents the intra-line difference between two strings.

# Example Python program that finds the difference
# between two lists of strings using the ndiff() function
# of difflib module
import difflib

# Create two lists of strings
textStrings1 = ["Hello", "World"]
textStrings2 = ["Hello", "Friends"]

# Find the differences
diffs = difflib.ndiff(textStrings1, textStrings2)

print(diffs)
print(type(diffs))
# Print each difference
for diff in diffs:
print(diff)
