I'm following Corey Schafer's tutorial and it all works well on his end but this is what happens on mine...

first, I created flaskblog file
from flask import Flask, render_template
app = Flask(__name__)
posts = [
{
'author': 'Corey Schafer',
'title': 'Blog Post 1',
'content': 'First post content',
'data_posted': 'April 20, 2018'
},
{
'author': 'Jane Doe',
'title': 'Blog Post 2',
'content': 'Second post content',
'date_posted': 'April 21, 2018'
}
]
@app.route("/")
@app.route("/home")
def home():
return render_template('home.html', posts=posts)
@app.route("/about")
def about():
return render_template('about.html', title=About)
if __name__ == '__main__':
app.run(debug=True)then home page <!DOCTYPE html>
<html>
<head>
{% if title %}
<title>Flask Blog - {{ title }}</title>
{% else %}
<title>Flask Blog</title>
{% endif %}
</head>
<body>
{% for post in posts %}
<h1>{{ post.title }}</h1>
<p>By {{ post.author }} on {{post.date_posted}} </p>
<p>{{ post.content }}</p>
{% endfor %}
</body>
</html> and about page <!DOCTYPE html>
<html>
<head>
{% if title %}
<title>Flask Blog - {{ title }}</title>
{% else %}
<title>Flask Blog</title>
{% endif %}
</head>
<body>
<h1>About Page</h1>
</body>
