The file operation program is not updating

def update_server_config(file_path, key, value):
# Read the existing content of the server configuration file
with open(file_path, 'r') as file:
lines = file.readlines()

# Update the configuration value for the specified key
with open(file_path, 'w') as file:
for line in lines:
# Check if the line starts with the specified key
if key in line:
# Update the line with the new value
file.write(key + "=" + value + "\n")
print("File update successfully")
else:
# Keep the existing line as it is
file.write(line)
print("No change done")

# Path to the server configuration file
server_config_file = 'server.conf'

# Key and new value for updating the server configuration
key_to_update = 'PORT'
new_value = '9000' # New maximum connections allowed

# Update the server configuration file
update_server_config(server_config_file, key_to_update, new_value)

This program is running but it is not updating to new value.

Start with update_server_config in the issue body and inspect the referenced server.conf to compare its contents with the key and value passed to the function. Run the program against that file and verify that the PORT setting contains 9000 afterward. The issue does not include the configuration file or an error, so reproduce the behavior before narrowing the cause.
