Introduction

When storing and transforming data for humans to see, string formatting can become very important. Python offers a wide variety of string formatting methods which are outlined in this topic.

Syntax

• “{}”.format(42) ==> “42”
• “{0}”.format(42) ==> “42”
• “{0:.2f}”.format(42) ==> “42.00”
• “{0:.0f}”.format(42.1234) ==> “42”
• “{answer}”.format(no_answer=41, answer=42) ==> “42”
• “{answer:.2f}”.format(no_answer=41, answer=42) ==> “42.00”
• “{[key]}”.format({‘key’: ‘value’}) ==> “value”
• “{[1]}”.format([‘zero’, ‘one’, ‘two’]) ==> “one”
• “{answer} = {answer}”.format(answer=42) ==> “42 = 42”
• ’ ’.join([‘stack’, ‘overflow’]) ==> “stack overflow”
