Write a program that finds word differences between two sentences. The input begins with the first sentence and the following input line is the second sentence. Assume that the two sentences have the same number of words.
The program displays word pairs that differ between the two sentences. One pair is displayed per line.
Ex: If the input is:
Smaller cars get better gas mileage
Tiny cars get great fuel economy
then the output is:
Smaller Tiny
better great
gas fuel
mileage economy
Hint: Store each input line into a list of strings.
Here is my code:
s1 = input()
s2 = input()
w1 = s1.split()
w2 = s2.split()
for i in len(w1):
if (w1[i] != w2[i]):
print(w1[i],w2[i])
and this is what i got
Traceback (most recent call last):
File "main.py", line 7, in <module>
for i in len(w1):
TypeError: 'int' object is not iterable
put range() before len:
s1 = input()
s2 = input()
w1 = s1.split()
w2 = s2.split()
for i in range(len(w1)):
if (w1[i] != w2[i]):
print(w1[i],w2[i])
#output
Smaller cars get better gas mileage
Tiny cars get great fuel economy
Smaller Tiny
better great
gas fuel
mileage economy
The error in the code for i in len(w1): is that len(w1) returns the length of the list w1, which is an integer, and range() is expected as the argument for the for loop.
Code:
# Hint given: Store each input line into a list of strings.
s1=list(map(str,input().split(" "))) #This is how you can store in the list.
s2=list(map(str,input().split(" ")))
for i in range(len(s1)): #As given in the question The two sentences have the same number of words. there is no worry of index out of range..!
if(s1[i] != s2[i]):
print(s1[i],s2[i])
Output:
Smaller cars get better gas mileage
Tiny cars get great fuel economy
Smaller Tiny
better great
gas fuel
mileage economy

def bill_cal():

bill_cal()
I am trying to cast float on each item obtained from bill_amount.split(","), and perform the bill_cal() function, but got below error:
How much is the bill? You can enter multiple bills separarted by comma.
100,200
Is there any credit card cashback on the bills? 2% = 0.02
.02
How many people are splitting the bill?2
Traceback (most recent call last):
File "main.py", line 10, in <module>
bill_cal()
File "main.py", line 2, in bill_cal
split_amount = bill_amount_list * (1-cashback_rate) / person_split_no
TypeError: can't multiply sequence by non-int of type 'float'
You are "multiplying" your bill_amount_list which is... well, a list. Sequences can be "multiplied" by int (meaning you will repeat the sequence), but not by float, hence your error.
Pass your bill to the function, and use it in the computation:
def bill_cal(amount):
split_amount = amount * (1-cashback_rate) / person_split_no
#...
for bill in map(float,bill_amount_list):
bill_cal(bill)
You need to call the function with a local variable.
Also it's good practice to check your input as well like this:
if item.isnumeric():
'call the function'
I want to create a game where a person is drawn out randomly.
Can some1 check the code if everything is setup correctly.
I have tested the code numerous times and its ok in my eyes.
But when I send the code to a review, to an online class I only get 50% score.
import random
# 🚨 Don't change the code below 👇
test_seed = int(input("Create a seed number: "))
random.seed(test_seed)
# Split string method
names_string = input("Give me everybody's names, separated by a comma. ")
names = names_string.split(", ")
# 🚨 Don't change the code above 👆
#Write your code below this line 👇
print(names)
names_count = len(names)
random_name_number = random.randint(0, names_count)
print(f"{names[random_name_number]} is going to buy the meal today!")
The problem here is almost certainly with randint. Unlike most Python conventions, the parameters to randint are inclusive. That means, if you supply (0,10), you are going to get numbers from 0 to 10. In your case, if they supply 10 names, using index 10 is going to cause an exception.
You want random.randrange, not random.randint. randrange(0,10) will supply numbers from 0 to 9.
I am having a lot of trouble with writing the totals to a new file. When I run this code, it gives me an error code like this:

I have tried surrounding the list with square brackets. I have also tried converting the sum of each list into a string, but I get the same result. What can I do?

You reassigned str here:
str=line.split()
Never name a variable str, list, or any other builtin name -- it will lead to confusing bugs exactly like this one! Running a linter on your code will help you catch things like this.
For what it's worth, using str and + to compose a string is generally considered "unpythonic". Using an f-string is easier:
OutputFile.write(f"The total amount of money you spent on food is ${round(FoodTotal,2)}.\n")
You're overriding the built-in str on str=line.split() change it to something else. Also use f strings since you don't need to do the explicit type conversion:
OutputFile.write(f"The total amount of money you spent on food is ${round(FoodTotal,2)}. \n")
str=line.split() is your issue. You shadowed the built-in name str, replacing it with a list, so lines like str(round(FoodTotal,2)) thus would fail because str is not a function any longer.
I have written a program where a user get shown three types of bird food. Each bird food comes in 10kg and 50kg bags each with different prices. The prices are stored in a list:
Pellets = ['Pellets', 22.75, 100.00]
Mash = ['Mash', 20.50, 90.00]
Enhanced = ['Enhanced', 25.50, 125.50]
Size = ['10KG', '50KG']
I have current code where a user inputs their choice of feed, what size and how many bags. It then calculates the price by how many bags:
if ((foodtype) is '1' and (bagsize) is '1'):
print('$',((NumberOfBags)*Pellets[1]))
I am needing to write a if statement for a user to input there total amount of bird feed required and it tells how many bags of 50kg required and then the left over to be calculated into 10kg bags and for it to round up to a 10kg bag if a user inputs 52kgs required.
I expect the code to end up writing how many 50kg bags I need and how many 10kg bags I will require. e.g user says they need 134kg go bird feed the program will say you need 2 50kg bags and 4 10kg bags. Once this is worked out I plan to write how much the output will cost.
An if statement isn't the way to go about this. What you're describing is simple arithmetic.
kgs_required = 52
First do integer division to get the number of full 50kg bags.
n_50kg_bags = kgs_required // 50
This will give you 1x 50kg bag. Next get the modulo (remainder) from that division.
kg_remaining = kgs_required % 50
This will give you the 2kg left over. Now calculate the number of 10s in this number, rounding up with math.ceil
n_10kg_bags = math.ceil(kg_remaining / 10)
Which will give you 1x again. So for 52kg you require 1x 50kg and 1x 10kg bags.
I feel like perhaps there may be a better way to hold all these items, such as a list of dictionaries.
Consider each dictionary a real life object, and all it's contents to be properties (each property has a name and a corresponding value). If I want pellets, I would search for name = pellets and get the price value
For this, I would assume that each object is a product and it has all it's properties listed inside.
list_of_products = [
{ 'name': 'pellets', 'weight': 10, 'price': 22.75},
{ 'name': 'pellets', 'weight': 50, 'price': 100.00},
... more products
]
This way you can query this list and get what is selected, as shown by this article
I use Javascript more than Python, so here is the answer that makes sense to me (not the highest votes):
def search(name, people):
return [element for element in people if element['name'] == name]
To analyze the text, we transform it into a list P1 of words. Then we apply the Bigram methods and get a list X of couples of words (ai,bi) such that ai and bi occur one after another in P1 quite a lot of times. How to get in Python 3 a list P2 from P1 so that every two items ai and bi if they go one after another in P1 and (ai,bi ) from X would be replaced by one element ai_bi?
My ultimate goal is to prepare the text as a list of words for analysis in Word2Vec.
I have my own code and it works but I think it will be slow on big texts.
