Execution Sample

Digital Marketing

Users = 10
while Users < 50:
  Users += Users * 0.2
  print(Users)

This code shows how users grow by 20% each cycle, illustrating network effects increasing user base.

Analysis Table

Step	Users Before Growth	Growth (20%)	Users After Growth	Action
1	10	2	12	Users increase by 20%
2	12	2.4	14.4	Users increase by 20%
3	14.4	2.88	17.28	Users increase by 20%
4	17.28	3.46	20.74	Users increase by 20%
5	20.74	4.15	24.89	Users increase by 20%
6	24.89	4.98	29.87	Users increase by 20%
7	29.87	5.97	35.84	Users increase by 20%
8	35.84	7.17	43.01	Users increase by 20%
9	43.01	8.60	51.61	Users increase by 20%
Exit	51.61	-	-	Users reached above 50, loop stops

💡 Users exceed 50, condition Users < 50 becomes false, stopping growth loop.

Key Insights - 3 Insights

Why does the number of users grow faster as time passes?

Because each step adds 20% of the current users, the growth amount increases as the user base grows, shown in execution_table rows where growth values increase.

Why does the loop stop when users reach above 50?

The loop condition is Users < 50; once users exceed 50 (row 9), the condition is false, so the loop ends, as explained in the exit_note.

What does the network effect mean in this example?

It means the product becomes more valuable as more users join, causing faster user growth each cycle, reflected by increasing user numbers in the execution_table.

Visual Quiz - 3 Questions

Look at the execution_table at step 4. What is the number of users after growth?

A 20.74

B 17.28

C 24.89

D 14.4

💡 Hint

Check the 'Users After Growth' column in row 4 of the execution_table.

At which step does the number of users first exceed 50?

A Step 8

B Step 7

C Step 9

D Step 6

💡 Hint

Look at the 'Users After Growth' values in the execution_table rows.

If the growth rate changed from 20% to 10%, how would the users after growth at step 3 change?

A It would stay the same

B It would be lower than 17.28

C It would be higher than 17.28

D It would be exactly 20.74

💡 Hint

Lower growth rate means smaller increase each step; check the growth calculation in execution_table.

Concept Snapshot

Network effects mean a product becomes more valuable as more people use it.
Users attract more users, causing growth to speed up.
Growth can be modeled as increasing users by a percentage each cycle.
The cycle continues until a stopping condition is met.
This creates a positive feedback loop in marketing.

Full Transcript

Network effects in marketing happen when a product's value grows as more people use it. This causes more users to join, which makes the product even more valuable, attracting even more users. The process repeats, creating a cycle of growth. In the example, users start at 10 and grow by 20% each step. The number of users increases faster over time because the growth is a percentage of the current users. The loop stops when users exceed 50. This shows how network effects create a positive feedback loop that helps products grow quickly.
