How to assign two variables using a single string?-CodePudding

For example, if I have a base string "Hello <Name>, nice to meet you" and I want to personalize it for two or more people, with their own variable names, eg.

greeting_matt = "Hello Matt, nice to meet you"

greeting_henry = "Hello Henry, nice to meet you"

How do I do it in a single line, without code repetition?

CodePudding user response：

# Frist create a template
template = "Hello {name} with age {age}, nice to meet you"

# fill the placeholders
print(template.format(name="Matt", age=40))
print(template.format(name="Henry", age=42))

output:

Hello Matt with age 40, nice to meet you
Hello Henry with age 42, nice to meet you

CodePudding user response：

You can use str.format method; it formats the specified value and insert them inside the string's placeholder {}.

greeting = lambda name: "Hello {}, nice to meet you".format(name)

Output:

>>> greeting_matt = greeting('Matt')
'Hello Matt, nice to meet you'

>>> greeting_henry = greeting('Henry')
'Hello Henry, nice to meet you'
