- To create entirely new programs using string-based syntax.
- To modify or manipulate the data stored within a string variable. (correct)
- To convert numerical data into string format for output.
- To define new data types for storing text.
What happens if the characters specified in the replace method do not exactly match the characters in the original string?
What happens if the characters specified in the replace method do not exactly match the characters in the original string?
- The `replace` method will not perform any replacement, and the original string will remain unchanged. (correct)
- The `replace` method will replace the closest matching substring it can find.
- The `replace` method will automatically correct any misspellings and perform the replacement.
- The program will crash and display an error message.

Flashcards
Method (in programming)
Method (in programming)
Keywords that modify data within a variable; accessed using 'variable.method()'.
Lower and Upper Methods
Lower and Upper Methods
Methods to convert a string to lowercase or uppercase, respectively.
Replace Method
Replace Method
A method that substitutes specified characters in a string with new characters.
Study Notes
- Methods are keywords that modify data within a variable.
- To use a method, type the variable name, followed by a period, then the method name, and finally opening and closing parentheses:
string1.methodname() - Python includes prewritten methods.
Lower and Upper Methods
- The
lowermethod converts all characters in a string to lowercase. - The
uppermethod converts all characters in a string to uppercase. - These methods do not affect numbers or special characters.
Replace Method
- The
replacemethod changes specified characters in a string to something else. - It requires two strings inside the parentheses, separated by a comma.
- The first string is what you want to change, and the second is what you want to change it to.
- The characters inside the
replacemethod must exactly match the characters in the string for the method to work correctly.
