It looks like there are a few issues in your code snippet. Here's a corrected version that properly reads from the source file and writes to the target file:

```python
# Get the names of the source and target files from the user
print("Enter the Name of Source File: ")
source = input()
print("Enter the Name of Target File: ")
target = input()

# Open the source file for reading
try:
    with open(source, "r") as fp:
        texts = fp.readlines()
except FileNotFoundError:
    print(f"Error: The source file '{source}' does not exist.")
    exit()

# Open the target file for writing
with open(target, "w") as f:
    for line in texts:
        f.write(line)

print("\nFile Copied Successfully!")
```

### Key Changes Made:
1. **Variable Naming**: Changed the variable `sou` to `source` for clarity. Similarly, changed the loop variable from `sou` to `line` to avoid confusion.
2. **Error Handling**: Added a try-except block to handle the case where the source file does not exist.
3. **File Handling**: Used `with` statements to handle file operations, which ensures that files are properly closed even if an error occurs.
4. **Indentation**: Fixed the indentation in the loop to ensure that the `f.write(line)` line is properly indented.

This code will copy the contents of
 Here is the code snippet for copying the contents of a source file to a target file:
```python
print("Enter the Name of Source File: ")
sou = input()
print("Enter the Name of Target File: ")
target = input()

# Open the source file in read mode
with open(sou, "r") as fp:
    texts = fp.readlines()

# Open the target file in write mode
with open(target, "w") as f:
    for text in texts:
        f.write(text)

print("\nFile Copied Successfully!")
```
Note: The above code uses the `with` statement to open the files, which automatically closes the files after the block of code is executed. This is a more safer and recommended way to open files, instead of using `open()` and `close()` functions explicitly.
