CodePudding user response：

You could use for loop to iterate over lines of txtFile by split('\n') with break line and startswith to check if it start with '@' ot with closing curly brace '}' store lines in list and finally join them back with new line '\n' and show them with print!

txtFile = """
@Given
 User Username{
 User Userpassowrd 
 User ID 
 }
@When
User Username{
User Userpassowrd 
User ID 
}
@And
User Username{
User Userpassowrd 
User ID 
}
"""
output = []
for line in txtFile.split('\n'):
    if(line.startswith("@")):
        output.append('[' line)
    elif(line.strip().startswith("}")):
        output.append(line "],")
    else:
        output.append(line)
print('\n'.join(output)[0:-2])

Result:

[@Given
 User Username{
 User Userpassowrd
 User ID
 }],
[@When
User Username{
User Userpassowrd
User ID
}],
[@And
User Username{
User Userpassowrd
User ID
}]
