My code is as follows: (Inside of program all indentations are correct, I am returned with no errors)

import sys P= sys.argv[1] F= sys.argv[2] L= sys.argv[3] B= sys.argv[4]

# ---------------------------------------------------------------- # # Our Helper functions: # # ---------------------------------------------------------------- #Loads the file at filepath

# Returns a 2d array with the data

#

def load2dArrayFromFile(filepath): # Your code goes here: with open(filepath, 'r') as rfile: lines = rfile.read().split(' ') while '' in lines: lines.remove('') loadedArray = [line.split('|') for line in lines] return loadedArray

# Searches the 2d array 'records' for firstname, lastname.

# Returns the index of the record or -1 if no record exists

#

def findIndex(records, firstname, lastname): # Your code goes here: for line in records: if firstname == line[0] and lastname == line[1]: return records.index(line) return -1

# Sets the birthday of the record at the given index

# Returns: nothing

def setBirthday(records, index, newBirthday): # Your code goes here: line = records[index] line[2] = newBirthday records[index] = line

# Convert the 2d array back into a string

# Return the text of the 2d array

def makeTextFrom2dArray(records): # Your code goes here: writer = str() for line in records: writer += "|".join(line) + " " writer=' '+writer return writer

# ----------------------------------------------------------------

#

# Our main code body, where we call our functions.

#

# ----------------------------------------------------------------

# Load our records from the file into a 2d array records= load2dArrayFromFile(P) # Find out which index, if any, has the name we are hunting indexWeAreHunting= findIndex(records, F, L) # Set the birthday record to the one we were passed setBirthday(records, indexWeAreHunting, B) # Convert the records into a text string output= makeTextFrom2dArray(records) # Your code goes here # write the text string out to the file with open(P,'w') as wfile: wfile.write(output)

The output appears to be correct but it is not accepted. I can't seem to find the issue.

5. 5. Challenge: variable length records Variable Length Record Load the pipe-delimited file P It is organized with 3 fields on each line: firstname lastname birthday Search for the firstname F and lastname L replacing the birthday with B Write the file back out in the same pipe-delimited format
