Definition:
If you need to delete a value from a list, this method removes it from the list. When you delete any value, this method shifts the values to fill the empty position.
Note: It deletes the first occurrence of the value that you want to delete.
Now you will clearly understand the method through the flowchart .
List → a = [10, 20, 30, 20] Index : 0 1 2 3 ↓ ↓ ↓ ↓ Value : 10 20 30 20 ↑ (first occurrence) Method → a.remove(20) Removed → 20 ❌ After Remove → [10, 30, 20] Index : 0 1 2 ↓ ↓ ↓ Value : 10 30 20 Shift → 30 ← 20 ← ← (left shift)
Syntax
list_name.remove(value)Example:
a = [10, 20, 30, 20]
