Strings Operators and f-string

This video tutorial covers various string operations in Python, including concatenation, data type conversion, and the use of built-in functions like len, index, count, and replace. It also explains how to convert strings to lowercase or uppercase and introduces F-strings for string formatting. The tutorial provides examples to demonstrate these concepts, ensuring a comprehensive understanding of string manipulation in Python.

What is the result of concatenating a string with an integer without type conversion in Python?

• The integer is ignored.

• Python throws an error.

• The integer is added to the ASCII value of the string.

• The integer is automatically converted to a string.

Which function would you use to find the number of characters in a string?

• find()

• len()

• index()

• count()

If a character appears multiple times in a string, what does the index function return?

• The index of the last occurrence.

• The index of the first occurrence.

• An error message.

• The total number of occurrences.

Which function is used to replace a substring within a string?

• change()

• substitute()

• replace()

• swap()

What is the purpose of an F-string in Python?

• To convert strings to uppercase.

• To find the frequency of a character.

• To concatenate strings without spaces.

• To format strings with placeholders.
