Day 7: Python User Input, Type Conversion

Question 1

What does the input() function do?

Takes input from the user Displays output to the user Converts input to an integer Stops the program

Question 2

What is the data type of input received using input()?

int float str Depends on input

Question 3

What will be the output? age = input("Enter age: ") print(type(age))

<class 'int'> <class 'float'> <class 'str'> Error

Question 4

Which line correctly converts user input to an integer?

age = int(input()) age = input(int()) age = input().int() age = str(input())

Question 5

What will happen? num1 = input("Enter number: ") num2 = input("Enter number: ") print(num1 + num2) User enters: 5 and 3

8 53 5 3 Error

Question 6

How do you fix the previous code to get 8?

print(int(num1) + int(num2)) print(float(num1 + num2)) print(num1 * num2) No fix needed

Question 7

What will this print? price = float(input("Enter price: ")) qty = int(input("Enter quantity: ")) print(price * qty)

Always an integer Always a string A numeric result Error

Question 8

Which is the correct way to print user data using f-strings?

print("Name: {name}") print(f"Name: {name}") print("fName: name") print(name)

Question 9

What will this code do? password = input("Enter password: ") if len(password) >= 8: print("Valid password") else: print("Invalid password")

Checks if password contains numbers Checks if password length is at least 8 Checks if password is encrypted Always prints Valid

Question 10

Why is validation usually written inside a function?

To slow down the program To reuse the logic To avoid input() Functions are mandatory

Question 11

Which function correctly validates password length? def is_valid(password): return len(password) >= 8

Returns True for short passwords Returns False for valid passwords Returns True for valid passwords Causes an error

Question 12

What does this function return? def check_age(age): if age >= 18: return "Adult" return "Minor" If age = 20

True False Adult Minor

Question 13

Which creates a multi-line formatted output?

print("Name: ", name, "Age: ", age) print(f"Name: {name}\nAge: {age}") print("Name: {name}\nAge: {age}") print(name age)

Question 14

Which is best for a Client Registration Form?

Hardcoded values Only variables User input + validation Comments

Question 15

Which statement is TRUE?

User input can only be text Calculations can’t be done on input Input must be converted for math input() returns numbers automatically
