Question

differentiate between identifiers and keywords​

Answer 1

Identifiers and keywords are both components of Python IDLE.

IDENTIFIERS:

• Identifiers are unique names given to a variable.
• They identify the name of a entity when asked.
• Can consist of letters, numbers and underscores; no other special character can be used.
• They aren't case sensitive.

Examples:

XID, high_score, bot, etc.

KEYWORDS:

• They are reserved words in the program.
• They specify the operation/command requested.
• Can consist of only letters.
• Case sensitive [lowercase]; True, None and False are the only keywords having a higher case.
• No special character can be used.

Examples:

int, or, and, if, etc.

Answer 2

KEYWORDS: The reserved words of python which have a special fixed meaning for the interpreter are called keywords. No keywords can be used as an identifier.

IDENTIFIER: The name of any variable constant function or module is called as an identifier.
