Codio challenge

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.

# Get the filepath from the command line 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:

#open the file in read mode with open(filepath, 'r') as rfile: totallines = rfile.read().split(' ')

while '' in totallines: totallines.remove('')

loadedArray = [eachline.split('|') for eachline in totallines]

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 eachline in records: if firstname == eachline[0] and lastname == eachline[1]: return records.index(eachline)

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]

#store the birthday date 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:

filewriter = str()

for eachline in records: filewriter += "|".join(eachline) + " "

return filewriter

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

#

# 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)
