I'm getting the wrong output in my if statment

I'm new to python and am trying to fix this and By defualt its running the else statment I don't understand and need help. I'm new so please dumb your answers down to my -5 iq
menu = "Baguette , Crossiant , Coffee , Tea , Cappuccino "
print(menu)
if "" > menu:
order = input("What Would you like? \n ")
amount = input("How many " + order + " would you like?")
print( name + " Your " + amount + " " + order + " will be ready soon!\n\n\n")
price = int(4)
#converts number into intenger to do math correctly (int)
total = price * int(amount)
#turns total into string intead of intenger to prevent error in terminal
print("Thank you, your total is: $" + str(total))
print("Your " + amount + " of " + order + " is ready!")
print("Please enjoy you " + order + "!")
print("Please come again!")
else:
#If not on menu stops running
print("Sorry Thats not on the menu")
quit()
I changed the if "" to on_menu and list the options but it didn't work, and I asked people on discord.

menu = ["Baguette" , "Crossiant" , "Coffee" , "Tea" , "Cappuccino "]
count = 0
for item in menu:
print(str(count) +" -> "+str(item))
count += 1
order = int(input("\n What Would you like? \n "))
if order > len(menu) or order < 0 or order == "" or not menu[order]:
print("Sorry Thats not on the menu")
quit()
orderCount = int(input("How many " + menu[order] + " would you like?"))
print("Your " + str(orderCount) + " " + menu[order] + " will be ready soon!\n\n\n")
amount = int(4) * int(orderCount)
print("Thank you, your total is: $" + str(amount))
print("Your " + str(amount) + " of " + str(menu[order]) + " is ready!")
print("Please enjoy you " + str(menu[order]) + "!")
print("Please come again!")

Currently you are not checking the user input, you are just checking for a False statement based on what you defined. You need to check if the user input is on the menu, else quit the program.
menu = "Baguette , Crossiant , Coffee , Tea , Cappuccino "
print(menu)
name = input("What your name? \n ")
order = input("What Would you like? \n ")
if not order.lower() in menu.lower(): # checking if user input is in the menu
#If not on menu stops running
print("Sorry Thats not on the menu")
quit()
amount = input("How many " + order + " would you like?")
print( name + " Your " + amount + " " + order + " will be ready soon!\n\n\n")
price = int(4)
#converts number into intenger to do math correctly (int)
total = price * int(amount)
#turns total into string intead of intenger to prevent error in terminal
print("Thank you, your total is: $" + str(total))
print("Your " + amount + " of " + order + " is ready!")
print("Please enjoy you " + order + "!")
print("Please come again!")

#input name
name = input("What is your name?\n")
#create menu
menu = "Baguette, Crossiant, Coffee, Tea and Cappuccino"
#display menu
print(menu)
#input order
order = input("What would you like?\n")
#if the order item is in the menu
if order in menu:
#input quantity
amount = input("How many " + order + "s would you like? ")
#display message
print( name + " Your " + amount + " " + order + " will be ready soon!\n\n\n")
#setting price of all items to 4
price = 4
#calculating total
total = price * int(amount)
#turns total into string intead of intenger to prevent error in terminal
print("Thank you, your total is: $" + str(total))
print("Your " + amount + " of " + order + " is ready!")
print("Please enjoy you " + order + "!")
print("Please come again!")
#if the item is not in menu
else:
#display message
print("Sorry Thats not on the menu")
Hope this helps! I have added the explanation as comments.

Python is asking for me to indent, but when I do, the line doesn't work. What should I do?

I was wondering about a specific problem I was having while writing a program. The program is very simple. Ask for some info about the person with some input functions, and then compile the information into one paragraph, summarizing some info about the person.
Here's some code (I'll explain after):
def main():
userName = input("What's your name?")
userAge = input("How old are you?")
userNumber = input("What's your favorite number?")
userAnimal = input("What's your favorite animal?")
print("Hi, my name is" + userName + "and I'm" + userAge + ".")
print("My favorite number is" + userNumber + "and my favorite animal is" + userAnimal + ".")
main()
Python keeps asking me to indent the line "userName = input("What's your name?")", so I did that. But when I do that, the line just flat out disappears from when I run it.

You meant to write :
def main():
userName = input("What's your name?")
userAge = input("How old are you?")
userNumber = input("What's your favorite number?")
userAnimal = input("What's your favorite animal?")
print("Hi, my name is : " + userName + " and I'm " + userAge + ".")
print("My favorite number is : " + userNumber + " and my favorite animal is " + userAnimal + ".")
main()

You have to indent the content of the main function.
def main():
userName = input("What's your name?")
userAge = input("How old are you?")
userNumber = input("What's your favorite number?")
userAnimal = input("What's your favorite animal?")
print("Hi, my name is" + userName + "and I'm" + userAge + ".")
print("My favorite number is" + userNumber + "and my favorite animal is" + userAnimal + ".")
main()

How to access a specific student's information?

If the students.txt file was like this:
michael jackson:
Civil id: 102931023
Gender: male
In the show_student() function I knew only how to check if the student is in the file or not, but I couldn't access the student information.
How can I access to it?
Code
import csv
import sys
import pathlib
file_path = pathlib.Path("students.txt")
if file_path.exists():
pass
else:
file = open("students.txt", "a+")
def login():
username = input("Username: ")
password = input("Password: ")
if username == "a" and password == "b":
menu()
else:
print("Please try again.")
login()
def menu():
print("*" * 20 + " Main Menu " + "*" * 20)
print(" " * 20 + "A: Register student" + " " * 20)
print(" " * 20 + "B: Show students" + " " * 20)
print(" " * 20 + "C: Show specific student" + " " * 20)
print(" " * 20 + "D: Quit" + " " * 20)
print("*" * 20 + " Main Menu " + "*" * 20)
operation = input("Enter operation: ")
if operation.strip().lower() == "a":
register_student()
elif operation.strip().lower() == "b":
show_students()
elif operation.strip().lower() == "c":
show_student()
elif operation.strip().lower() == "d":
sys.exit()
else:
print("Invalid operation.")
menu()
def register_student():
student_civil_id = input("Student id: ")
student_first = input("Student first name: ")
student_last = input("Student last name: ")
student_gender = input("Student gender: ")
student_full = student_first + " " + student_last
with open("students.txt", "a+") as studentInfo:
info = [student_full + ": " + "\n Civil id: " + student_civil_id + "\n Gender: " + student_gender]
studentInfo.write("\n" + student_full + ": " + "\n Civil id: "
+ student_civil_id + "\n Gender: " + student_gender)
print("Student has been registered.")
def show_students():
with open("students.txt") as studentInfo:
print(studentInfo.read())
def show_student():
student_name = input("Student name: ")
with open("students.txt") as studentInfo:
if student_name.strip().lower() in studentInfo.read():
print("Student exists.")
else:
print("Student not exists.")
login()

I guess, you have many students in students.txt file as:
michael jackson:
Civil id: 102931023
Gender: male
james smith:
Civil id: 165468798
Gender: male
With this file, you can find the index of the specific student, split the text starting from that index, and take the first 3 items from the returned list. At the end, you can use join() function while printing.
def show_student():
student_name = input("Student name: ")
with open("students.txt") as f:
text = f.read()
student_position = text.find(student_name.strip().lower())
if student_position != -1:
info = "\n".join(text[student_position:].split("\n")[:3])
print("Student information:")
print(info)
else:
print("Student does not exists.")

use a regular expression to match the block of information
import re
form = r'{}:\nCivil id: \d+\nGender: [a-z]+'
def show_student():
student_name = input("Student name: ")
with open("students.txt") as studentInfo:
name = student_name.strip().lower()
pat = re.compile(form.format(name), re.MULTILINE)
try:
print(pat.findall(studentInfo.read())[0])
except:
print("Student does not exist.")

You could change your def to something like:
def show_student():
student_name = input("Student name: ")
with open("students.txt") as studentInfo:
studentData = studentInfo.readLines()
if len(studentData) > 0 and student_name.strip().lower() in studentData[0]:
print(*studentData[1:])
else:
print("Student not exists.")
To make your life easier, you might want to look into creating structured data using json, xml, csv or something similar. How do you know that michael jackson: is a name?

Number is adding to file but not appearing when I print it

This is my entire code block but I am just having trouble making the scores show after the game is played. The score is being added to the file correctly, but when I go to print the scores, the new score is not appearing, even though I have appended it. How can I fix my code to make it show up? I am new to coding so anything helps. I think this is an easily solvable error, but I don't know how to fix it. Thank you!

You never update scoreslist to have sum in it (either by appending it or by reading scoreslist out of the file again). Add a line that adds sum to scoreslist:
add_file_contents(scoreslist_path, '\n' + str(sum))
scoresline.append(sum)

Can someone scan over this Python code that I wrote and let me know what I did wrong?

I have to write a program for my Computer Logic class, and I can't figure out why this won't run. The error I keep getting is IndentationError: expected an indented block (<string>, line 3) Can someone please point me in the right direction? If there are any mistakes you find, please let me know. This code has to be able to run properly. Thanks.

Your code is missing indentation after the first while. You need to indent the statements that will run within this loop, also do the same with the second while you have on line 9.

In Python, after a colon must indent(recommend 4 space). So the indent should be like this:
while True:
cname = 'My Company'
drate = .17
maxhrs = 40
pdate = "9/1/2015"
orate = 1.5
lc = 'Y'
while(lc == 'Y'):
ename = raw_input("Enter employee's name.")
dcode = raw_input("Enter department code.(1 - Shipping 2 - Mngmt.)")
hworked = float(raw_input("Enter total hours worked."))
prate = float(raw_input("Enter your pay rate."))
inscost = float(raw_input("Enter the cost of insurance."))
city = float(raw_input("Enter your city code.(1 - Sumiton 2 - Hamilton)"))
st = raw_input("Enter your state")
sex = raw_input("Enter your sex.(M - Male F - Female)")
yrsemp = raw_input("Enter total years employed.")
print("Welcome to our company: ", cname)
print("Pay period date: ", pdate)
if(sex == 'M'):
sexword = 'Male'
else:
sexword = 'Female'
print("Employee name: ", ename, "Sex: ", sexword)
if(city == '1'):
cityn = 'Sumiton'
else:
cityn = 'Hamilton'
print("City: ", cityn, "State: ", state)
if(dcode == '1'):
dname = 'Shipping'
else:
dname = 'Management'
print("Department name: ", dname)
rpay = maxhrs * prate
print("Regular pay: ", rpay)
opay = [(maxhrs - hworked) * orate] * prate
print("Overtime pay: ", opay)
gross = rpay + opay
print("Gross before deduction: ", gross)
damt = drate * gross
print("Deduction amount: ", damt "Insurance cost: ", inscost)
npay = gross - (damt + icost)
print("Net pay: ", npay)
new = raw_input("Would you like to start over with a new person? yes/no")
if(new = 'yes')
restart = int(input("Press 1 to try again, 0 to exit. "))
if(restart == '1'):
continue
elif(restart == '0'):
break

(by the way, your code has a lot of problems...I can't even understand this is Python 3 or Python 2...)
