# 1. The textfile, travel_plans.txt, contains the summer travel plans for someone with some commentary.

fileref = open("travel_plans.txt","r")
num = 0
for i in fileref:
    num += len(i)
fileref.close()

# 2. We have provided a file called emotion_words.txt that contains lines of words that describe emotions.
# Find the total number of words in the file and assign this value to the variable num_words.

num_words = 0
fileref = "emotion_words.txt"

with open(fileref, 'r') as file:
    for line in file:
        num_words += len(line.split())

print("number of words : ", num_words)

# 3. Assign to the variable num_lines the number of lines in the file school_prompt.txt.

num_lines = sum(1 for line in open('school_prompt.txt'))

# 4. Assign the first 30 characters of school_prompt.txt as a string to the variable beginning_chars.

f = open('school_prompt.txt', 'r')
beginning_chars = f.read(30)
print(beginning_chars)

# 5. Challenge: Using the file school_prompt.txt, assign the third word of every line to a list called three.

three = []

with open('school_prompt.txt', 'r') as f:
    three = [line.split()[2] for line in f]
    print(three)

# 6. Challenge: Create a list called emotions that contains the first word of every line in emotion_words.txt.

fileref = open ("emotion_words.txt","r")
line = fileref.readlines()
emotions = []
for words in line:
    word = words.split()
    emotions.append(word[0])
print (emotions)

# 7. Assign the first 33 characters from the textfile, travel_plans.txt to the variable first_chars.

f = open('travel_plans.txt', 'r')
first_chars = f.read(33)
print(first_chars)

# 8. Challenge: Using the file school_prompt.txt, if the character ‘p’ is in a word, then add the word to a list called p_words.

fileref = open('school_prompt.txt', 'r')
words = fileref.read().split()
p_words = [word for word in words if 'p' in word]

"""

 """
 
with open('school_prompt.txt', 'r') as fileref:
    three = [line.split()[2] for line in fileref]
    
print(three)

This solution uses list comprehension.

"""

"""

with open('school_prompt.txt', 'r') as fileref:
    p_words = [word for line in fileref for word in line.split() if 'p' in word]
    
print(p_words)

filere = open('school_prompt.txt', 'r')
words = fileref.read().split()
p_words = [word for word in words if 'p' in word]

I got error in this code can you tell me why?

My take on:
Challenge: Create a list called emotions that contains the first word of every line in emotion_words.txt.

file = open("emotion_words.txt", "r")
emotion_words = file.readlines() #read lines
print(emotion_words) #all lines appear
emotions = [] #new list to accumulate first word of every line

for line in emotion_words: #iterate every line separately in sequence
line = line.split() #split the line first to work each one independently
print(line) #first line appears
emotions.append(line[0]) #add the first word from the first line to the list emotions
print(emotions) #the first word appears

print(emotions)

Could someone explain line 60 of the code to me, thanks..

p_words = []
with open('school_prompt.txt','r') as sp:
sp_1 = sp.read().split()
for word in sp_1:
if 'p' in word:
p_words.append(word)
print(p_words)
print("There are {} words that have p.".format(len(p_words)))

does anyone have the txt files? I already took the course and I'm refreshing my memory but I can't find the txt files and I don't want to pay just to have access to the files, it would be much appreciated :)
