TXT Self-study tutorial

Answer 1

The following is a self-taught tutorial on TXTS files:

** 1. Creation of TMT file **
1. ** Using notepad (on the Windows system)**
- Open notepad: Search for "notepad" and open it by clicking on the "Start" menu.
- Enter text: Enter the content you want to save in the open notepad window.
- Save the file: click the "file" menu and choose "save" or "save as". In the pop-up dialog box, choose the save location, enter the file name, ensure that the file type is "All files" or "text file", and save it with ".txt" as the file extension.
2. ** Using the right-click menu (on the Windows system)**
- Choose a folder: Find the folder in the file explorer where you want to create the TMT file.
- Right-click: Right-click in the blank space of the folder, select New- > Text document, and then renamed it to the desired file name (make sure the file name ends with ". txt').
3. ** Using Command Line (on the Windows system)**
- Open the command prompt: press the "Win+R" key, type "Cmd" and enter.
- To navigate to the target folder: use the "CD" command to switch to the folder where you want to save the TMT file, for example,"CD C: User sYourUser name Files".
- Create a file: Enter the command "echo Your text here > filename.txt." Then replace "Your text here" with the content you want to enter,"filename.txt." with the file name you want, and press the enter key.

** 2. Basic operations of TMT files (Python as an example)**
1. ** Read the entire file **
- Code sample:
```python
path =r'D: #path where the txtfile is located
with open(path, 'r') as file:
content = file.read()
print(content)
```
2. ** Read line by line **
- Code sample:
```python
path =r'D:\file.txt'
with open(path, 'r') as file:
lines = file.readlines()
print(lines)#Print a list of results to display each line of content
```
3. ** Iterates by row **
- Code sample:
```python
path =r'D:\file.txt'
with open(path, 'r') as file:
for line in file:
print(line, end='')
```
4. ** Write over (Create if the file doesn't exist, clear the file content and write new content if the file exists)**
- Code sample:
```python
path =r'D:\file.txt'
with open(path, 'w') as file:
file.write('Hello, World!\ n')
```
5. ** Additional Write **
- Code sample:
```python
path =r'D:\file.txt'
with open(path, 'a') as file:
file.write('Hello')
```
6. ** Remove the specified line (process data in memory)**
- Code sample:
```python
path = r'D: #replace with the actual file path
line_to_remove = 3#line number to be removed (1 - based)
try:
with open(path, 'r') as file:
lines = file.readlines()
if 1 <= line_to_remove <= len(lines):
del lines[line_to_remove - 1]
else:
print(f"Line number {line_to_remove} is out of range. ")
with open(path, 'w') as file:
file.writelines(lines)
except FileNotFoundError:
print(f"The file {path} does not exist. ")
except Exception as e:
print(f"An error occurred: {e}")
```
7. ** Check if the file exists **
- Code sample:
```python
import os
path =r'D:\file.txt'
if os.path.exists(path):
print('File exists. ')
else:
print('File does not exist. ')
```

** 3. Split the TMT file (using specific software)**
1. ** Split by line count (use the first assistant editor expert)**
- He opened the software and entered the "text batch operation" section.
- import the TMT document to be split (can be imported in bulk).
- In the function bar, select the "Split Text" function.
- Choose the splitting mode as needed, such as "Divide into x files evenly according to the total number of rows", and set the number of rows per file.
- Choose the path to save the split file.
- He clicked the "Split the text in batches" button to split the text, and then he checked the splitting result.
2. ** Split the content according to the partition (use the first assistant editor expert)**
- He opened the first assistant editor software and entered [Text Mass Operation]- >[Split Text].
- Choose [Split by Separating], then select [Do not keep the separated content after splitting], and then enter the separated content (for example, entering the Enter key multiple times means separating by a blank line).
- Add the files that you want to split in batches. After selecting the save method, click [Split Text in Batches] to view the splitting results.
