symbols = input()
for word in words:
  if symbols in word:
    print(word)

Answer

Code Explanation

The provided code snippet is written in Python and is designed to filter and print words from a list based on user-inputted symbols or substrings. Below is a structured breakdown of the code.

Code Breakdown

1. Variable Initialization

words = ["семь", "семнадцать", "пропуск", "прочее", "печенье"]
  • Purpose: This line defines a list named words containing five strings. Each string is in Russian and represents different words.
  • Type: The variable words is a list, which is a data structure in Python that can hold multiple items.

2. User Input

symbols = input()
  • Purpose: This line prompts the user to enter a string. The input is stored in the variable symbols.
  • Type: The input is received as a string.

3. Loop through Words

for word in words:
  • Purpose: This line initiates a loop that iterates through each item (word) in the words list. For every iteration, the variable word represents the current word being processed.
  • Type: The loop executes for as many times as there are items in the words list.

4. Conditional Statement

if symbols in word:
  • Purpose: This line checks whether the string stored in symbols is a substring of the current word. The in operator checks for the presence of the substring.
  • Behavior: If the condition evaluates to True, the code inside the following block (the print statement) will execute.

5. Print Matching Words

print(word)
  • Purpose: If the condition in the previous line is met (i.e., symbols is found within word), this line prints the current word to the console.
  • Output: The output will be the words from the list that contain the substring provided by the user.

Summary of Functionality

The complete code snippet performs the following operations:

  • Initializes a list of words in Russian.
  • Takes user input for a substring.
  • Iterates over the list of words to check if the user's substring appears in each word.
  • Prints any words that contain the user's substring.

Example Usage

If a user inputs the substring "сем", the output will be:

семь
семнадцать

This reflects that both "семь" and "семнадцать" contain the substring "сем".

Key Concepts

  • Lists: A mutable ordered collection that can store multiple items of different types.
  • Input Function: Used to read data from user input.
  • Looping: Utilizing for loops to process each item in a collection.
  • Conditional Statements: Using if statements to control the flow based on conditions.

This code serves as a simple example of text searching within a list, which could be extended or modified for various applications such as filtering databases or creating search functions.
