Output of string length and membership test

What is the output of this Python code?

Python

s = "hello world"
result = len(s) > 5 and 'w' in s
print(result)

A False

B TypeError

C SyntaxError

D True

💡 Hint

Check if the string length is greater than 5 and if the character 'w' is inside the string.

The string 'hello world' has length 11, which is greater than 5, and it contains the character 'w'. So both conditions are True, making the result True.

Check membership and length in a string

What will be printed by this code?

Python

text = "Python3.12"
output = ('3' in text) and (len(text) == 9)
print(output)

A NameError

B True

C False

D IndexError

💡 Hint

Check if '3' is in the string and if the length equals 9.

The string 'Python3.12' contains '3' but its length is 10, not 9, so the expression evaluates to False.

Result of combined string length and membership test

What is the output of this code snippet?

Python

s = "DataScience"
result = (len(s) < 10) or ('a' not in s)
print(result)

A False

B True

C SyntaxError

D TypeError

💡 Hint

Evaluate both conditions and then the or operation.

The length of 'DataScience' is 11, so len(s) < 10 is False. The character 'a' is in the string, so 'a' not in s is False. False or False is False.

Output of membership test with string length check

What does this code print?

Python

word = "challenge"
print(len(word) == 9 and 'z' in word)

A False

B True

C SyntaxError

D IndexError

💡 Hint

Check the length and if 'z' is in the string.

The length of 'challenge' is 9, so len(word) == 9 is True. But 'z' is not in the string, so 'z' in word is False. True and False is False.

Understanding string membership and length logic

Given the code below, what is the value of variable result after execution?

Python

text = "OpenAI GPT"
result = (len(text) != 10) and (' ' in text) and ('A' in text)

A True

B False

C TypeError

D NameError

💡 Hint

Check each condition carefully and combine with 'and'.

The string 'OpenAI GPT' has length 10, so len(text) != 10 is False. Since the first condition is False, the whole 'and' expression is False regardless of the others.
