💡 Hint

Common Mistakes

Passing the field name without quotes causes a NameError.

Using dictionary access like form['username'] inside get() is incorrect.

The request.form.get() method expects the form field name as a string. So, you need to pass 'username' as a string.

💡 Hint

Common Mistakes

Importing Flask instead of request.

Importing unrelated functions like render_template or redirect.

You need to import request from Flask to access form data inside routes.

3fill in blank

hard

Fix the error in the route to correctly access form data for 'email'.

Flask

@app.route('/submit', methods=['POST'])
def submit():
    email = request.[1]['email']
    return f"Email: {email}"

Drag options to blanks, or click blank then click option'

Aform

Bform.get

Cform.get()

Dform.get('email')

💡 Hint

Common Mistakes

Using form.get() with parentheses after form causes an error.

Trying to call get as an attribute incorrectly.

You should access request.form as a dictionary to get the value by key. Using request.form['email'] is correct.

4fill in blank

hard

Fill both blanks to create a route that handles POST requests and retrieves 'password' from form data.

Flask

@app.route('/login', methods=[[1]])
def login():
    password = request.form.get([2])
    return f"Password: {password}"

Drag options to blanks, or click blank then click option'

A'POST'

B'GET'

C'password'

D'userpass'

💡 Hint

Common Mistakes

Using 'GET' instead of 'POST' in methods.

Passing the wrong string or variable name to get() for the password.

The route must accept POST requests, so 'POST' is used in methods. To get the password from form data, pass the string 'password' to request.form.get().

5fill in blank

hard

Fill all three blanks to create a route that accepts POST, retrieves 'email' and 'name' from form data, and returns a greeting.

Flask

@app.route('/greet', methods=[[1]])
def greet():
    email = request.form.get([2])
    name = request.form.get([3])
    return f"Hello, {name}! Your email is {email}."

Drag options to blanks, or click blank then click option'

A'POST'

B'email'

C'name'

D'username'

💡 Hint

Common Mistakes

Using 'GET' instead of 'POST' in methods.

Mixing up form field names or using incorrect strings.

The route must accept POST requests, so 'POST' is used in methods. To get the email and name from form data, pass the strings 'email' and 'name' respectively to request.form.get().
