  • Description

    This solution would be more effitient for multiple writes, because of option "preopen".

     Code 
    class Solution:
    def __init__(self, data, filename='kumite776.txt', preopen=False):
        self.data = data
        self.filename = filename
        if preopen:
            self.file = open(self.filename, 'w')
        else:
            self.file = None
    
    def write_to_file(self):
        if not self.file:
            self.file = open(self.filename, 'w')
        self.file.write(self.data)
    Preloaded Code 
    def write_kumite_file(data):
    with open('kumite776.txt', 'w') as fo:
        fo.write(data)              
        

def open_file():
    with open('kumite776.txt') as fo:
        file = fo.read()
    return file

        
        
write_kumite_file('Hello Codewarz World!')
