def function(filename):
#opening a file for reading
my_file = open(filename, 'r')
#read the first line and stroe it to the variable choice
choice = my_file.readline()
#print the first line to the console/monitor
print(choice)
#close the file
my_file.close()
Thus the function will print only the first line of the input file. With the given file, the output will be

Problem 1 Recall that when the built-in function open() is called to open a file for reading, but it doesn't exist, an exception is raised. However, if the file exists, a reference to the opened file object is returned. Write a function safeOpen() that takes one parameter, filename - a string giving the pathname of the file to be opened for reading. When safeOpen() is used to open a file, a reference to the opened file object should be returned...

Write a function called backwards which takes two parameters. The first is a file object that has already been opened in read mode called essayfile. The second is called filename, which contains the filename for the output file that will need to be properly opened and closed in your function. The function should read from already opened file object line by line. Each line in the file should have the words on the line reversed. For example,...

Write a function called char_counter that counts the number of a certain character in a text file. The function takes two input arguments, fname, a char vector of the filename and character, the char it counts in the file. The function returns charnum, the number of characters found. If the file is not found or character is not a valid char, the function return -1. As an example, consider the following run. The file "simple.txt" contains a single line: "This...
In Python: LoadFile is a function that takes in a string (a filename) and then returns a list. The list is the contents of the file, where each element is a list of data from the file. Here's an example of using this function. The input file had four lines of text. >>> lines = LoadFile("test.txt") >>> print("OUTPUT", lines) OUTPUT ["Hello there", "I am a test file", "please load me in and print me out", "Thanks"]
This is a Python related question. My returned output from a function used finditer with a regex pattern to present data from text file. For cities that were blank, there were two dashes like this: “- -“ Those two dashes are being returned for City (?P<city>) since city is blank and that’s the value showing for it in text file. That makes sense; however I need it to pull back only 1 dash. Example: When city present in text file,...
In Python and in one file please. (Simple functions with an expressions) Create a function called load_inventory(filename). The filename argument in this case specifies the name of a file that contains all the inventory/product information for the store, including product names, descriptions, prices, and stock levels. This function should clear any information already in the product list (i.e., a fresh start) and then re-initialize the product list using the file specified by the filename argument. You can structure your file...
