# CSV Column Length Analyzer
2+
3+
This simple Python script analyzes a CSV file and determines the maximum length of each column. The script uses the `csv` module to read the CSV file and iterates through each row to find the maximum length for each column.
4+
5+
## Requirements
6+
7+
- Python 3.x
8+
9+
## Usage
10+
11+
1. Ensure you have Python installed on your system.
12+
13+
2. Download the script file (`script.py`) to your local machine.
14+
15+
3. Open a terminal or command prompt and navigate to the directory where the script is located.
16+
17+
4. Modify the `FILE_PATH` global constant to specify the path to your CSV file.
18+
19+
```python
20+
FILE_PATH = 'file.csv'
21+
```
22+
23+
5. Run the script:
24+
25+
```bash
26+
python script.py
27+
```
28+
29+
6. The script will print the maximum length of each column in the following format:
30+
31+
```plaintext
32+
Column 1 Max Length: X
33+
Column 2 Max Length: Y
34+
Column 3 Max Length: Z
35+
...
36+
```
