Here's a Python script that:
Reads each line from a file (test.txt).
Counts the number of visible characters (ignores \n).
Checks if the last visible character is a punctuation mark.
Saves the result to both a variable (results) and a new text file (result.txt).
It recognizes both Simplified and Traditional Chinese punctuation marks like：。！？；，“”‘’、《》 (plus some common full-width variants).
python# Define the set of Chinese punctuation marks (Simplified + Traditional)
chinese_punctuations = set('。！？；，“”‘’、《》（）…—')
results = []
# Read and process lines
with open('test.txt', 'r', encoding='utf-8') as f:
lines = f.readlines()
for line in lines:
stripped_line = line.strip() # Remove leading/trailing whitespace including \n
length = len(stripped_line)
ends_with_punctuation = 'y' if stripped_line and stripped_line[-1] in chinese_punctuations else 'n'
result_line = f'{length}, {ends_with_punctuation}'
results.append(result_line)
# Write to a new file
with open('result.txt', 'w', encoding='utf-8') as f:
for line in results:
f.write(line + '\n')
# Output results stored in the variable
print(results)
result.txt):6, y 15, n
Let me know if you want to include line numbers or more punctuation types.
Sure! Below is a Python script that:
Reads test.txt
Checks the length of each line (excluding the newline \n)
If the length is greater than the threshold, removes the trailing newline
If the length is less than or equal to the threshold, keeps the original line (including the newline)
Writes the result to filtered.txt
python# Define threshold
threshold = 10 # You can change this to any number
# Open input file and output file
with open('test.txt', 'r', encoding='utf-8') as infile, \
open('filtered.txt', 'w', encoding='utf-8') as outfile:
for line in infile:
stripped_line = line.rstrip('\n') # Remove only the newline character
length = len(stripped_line)
if length > threshold:
outfile.write(stripped_line) # Write line without newline
else:
outfile.write(line) # Write original line with newline
If test.txt contains:
bash生命真好！\n # 6 characters
我們去外頭走走，好好享受生命\n # 15 characters
And threshold = 10, then filtered.txt will contain:
生命真好！ 我們去外頭走走，好好享受生命
(Note: the second line has no newline at the end.)
Let me know if you'd like to preserve or remove trailing spaces, or make the behavior configurable!
