Hi I am new with Python and I can't seem to find the solution to this. I am using python with Flask to create a simple api to post and get products with name, price and isbn. On on the post method it gives me an issue on line 48 near " books.insert(0, new_book)". The error is: IndentationError: unindent does not match any outer indentation level
from flask import Flask, jsonify, request
app = Flask(__name__)
books =[
{
'name': 'Bill Gates',
'price': 8.99,
'isbn': 6546984984965161
},
{
'name': 'Steve Jobs',
'price': 6.99,
'isbn': 651468498494698
}
]
#Get /books/6546984984965161
# post books
#{
# "name": "Ana Banana",
# "price": 6.99,
# "isbn": 651468498494698
#}
def valid_book_object(book):
if "isbn" in book and "name" in book and "price" in book:
return True
else:
return False
@app.route('/books', methods=['GET', 'POST'])
def add_book():
# If request is GET, just return JSON data of books.
if request.method == 'GET':
return jsonify({'books': books})
else:
# This is part if it is POST request
request_data = request.get_json()
if valid_book_object(request_data):
new_book = {
"name": request_data['name'],
"price": request_data['price'],
"isbn": request_data['isbn']
}
books.insert(0, new_book)
return "True"
else:
return "False"
# GET /books/456
@app.route('/books/<int:isbn>') # second endpoint
def get_book_by_isbn(isbn):
return_value = {}
for book in books:
if book["isbn"] == isbn:
return_value = {
'name': book["name"],
'price': book["price"]
}
return jsonify(return_value)
return 'No book with {} isbn value'.format(isbn)
