# Exam Review 2022 Mar 26

# LABS
# Ch 3-13... all Labs!
# Ch 14-18 not as important, other than some good labs in Ch 15
# Ch 19-30 just LABS, but important practice!
# Use Submit Mode!!!

# Comp 1: Basic syntax and knowledge: operators, data types, etc
# Comp 2: Control Flow Structures
# Basic: if statements, loops, functions
# Adv: try/except and raising errors, classes
# Comp 3: modules, working with files

# Comp 1 Basic syntax and knowledge: operators, data types, etc
# Data Types
# int
# float
# str # strings
# list
# dict
# bool
# tuple # return x, y, z
# set # unordered, all unique values

# input() # returns a str
# # whitespace: " ", many Unicode variations, \r, \n, \t, \f
# myVar = input().strip() # or input().rstrip()
# myInt = int(input().strip())
# myList = input().strip().split(",") # if not splitting on default any whitespace

# Operators
# +
# -
# *
# /
# % # modulo!
# // # floor divison!
# ** # raise to a power, compare to math.pow()
# <
# >
# <=
# >=
# = # assignment
# == # asking
# !=
# +=
# -=
# # operator-like keyword
# and
# or
# in # if __ in _someContainer_
# not # if not __ in _someContainer__

# Comp 2 Control Flow Structures
# Basic
# IF statements: if, if/else, if/elif, if/elif/else
# LOOPS
# WHILE - basically an IF that repeats
# FOR - loop over a container, or some known number of times with range()
# for __ in __:
# for item in _someContainer_:
# for item in myList:
# for i in range(len(myList)): # myList[i], myStr[i]

# FUNCTIONS
# defining/writing vs calling
# parameters vs "regular" variables
# parameters vs arguments
# methods are functions that "belong" to a type
# a good function has ONE JOB, modular
# return vs print()

# def checkDuplicates(someList):
    # someList = # no! don't do this... the CALLS provide values

# lab question from Ch 7
# print('{:.2f}'.format(driving_cost(10, mpg, dpg)))
# print('{:.2f}'.format(driving_cost(50, mpg, dpg)))
# print('{:.2f}'.format(driving_cost(400, mpg, dpg)))

# BUILT-IN FUNCTIONS
# print()
# input()
# len()
# min()
# max()
# sum()
# sorted()
# reversed()
# range()
# open()
# round() # has 2 cousins in math: math.ceil(), math.floor()
# constructor/recasting functions
# int()
# float()
# list()
# dict()
# str()
# set()
# help() # you can use help() and dir() in the exam!
# dir()

# STRINGS
myString = "Just sit right back and you'll hear a tale."
# SLICING strings and list
# myString = myString[start, stop]
# revString = myString[::-1]

# STRING METHODS
# for item in dir(str):
#     if not item.startswith("_"):
#         print ("{}()".format(item))
# myString.format()
# myString.strip(), myString.rstrip()
# myString.split() # returns a list of smaller strings
# " ".join(listOfStrings)
# myString.replace(someStr, newStr) # to remove.. myString(someSub, "")
# myString.count(subStr) # return int
# myString.find(subStr) # returns int index
# case methods: myString.upper(), myString.lower()
# Boolean/is methods: myString.isupper(), myString.isdigit()

# LIST METHODS
# +
# myList.append(item)
# myList.insert(i, item)
# myList.extend(anotherList)
# # -
# myList.pop() # by index
# myList.remove() # by value
#
# myList.reverse()
# myList.sort()
# myList.count(item)

# DICTIONARIES
# myDictionary[key] # retrieve value for that key
# myDictionary[key] = value # kinda takes the place of update()
# for _key_ in someDictionary: # IN looks at the keys
#     # or for k, v in someDictionary.item():
# if _key_ in thisDictionary:
# myDictionary.keys()
# myDictionary.values()

# SETS
# mySet.add()
# mySet.remove() # by value
# mySet.pop() # removes a random entry!

# MATH MODULE
# import math
# math.e
# math.pi
# math.ceil()
# math.floor()
# math.sqrt()
# math.pow() # **, not to be confused with math.exp()
# math.factorial()

# full vs partial import
# from math import factorial #... factorial() not math.factorial()

# # aliased import
# import math as m #... m.factorial(), m.e

# # OPENING FILES
# good practice: Ch 12 Task 4, 7, 8
# I'll include these webinars in our follow up

# with open("filename.txt", "r") as f:
#     myContent = f.readlines() # returns a list of line by line strings

# import csv
# with open("mock_data.csv", "r") as f:
#     myReader = list(csv.reader(f))
# print(myReader)
# for line in myReader:
#     # print(line[2])
#     print("{} is at {}".format(line[3], line[4]))  # then we can get at positions within the line

# student questions
# Lab 31.21
import csv

# Type your code here.
filename = input().rstrip()
wordList = []

with open(filename, "r") as f:
    ufList = list(csv.reader(f))  # optional arg delimiter="\t"

# print(ufList)
for row in ufList:
    for word in row:
        if word not in wordList:
            print("{} {}".format(word, row.count(word)))  # here's where I missed the right paren of print() smh
            wordList.append(word)
