Python Programming Multiple Lines

Single line with more than 79 characters can be written in multiple lines

Line continuation character (\) to represent the line continuation.
total = item_one + \
        item_two + \
        item_three

Method definition or invoking part is more than 79 characters

Method definition or invoking part is more than 79 characters, then that line can be written in multiple lines as below

Array initialization in multiple lines

[], {}, or () brackets do not need to use the line continuation character.
list_var = ['one', 'two', 'three',
           'four', 'five'];
Example:
#!/usr/bin/python                                                               
                                                                                
list_var = ['one', 'two', 'three',                                              
            'four', 'five'];                                                    
list_var.append('six');                                                         
                                                                                
new_list_var = ['seven', 'eight'];                                              
list_var.extend(new_list_var);

Output:
