If Python matches a certain variable with a dictionary key value, you want to create a syntax that outputs a dictionary value. Help me, T...T

Q: If a certain variable value matches a dictionary key value with Python, you want to create a syntax that outputs a value value.

For example,

Season = "Spring" s_fruit = { 'Spring' : 'Strawberry', 'Summer' : 'Watermelon'}

Season's spring If the spring of s_fruit matches, This is an example where you want to print only the value 'strawberry'.

First of all, I write get in if, so it's printed as below.

if fruit_dir.get(season):

print(s_fruit.values())

-> [Strawberry, Plum] I think it's because it's printed only with the value of spring.

A matching value was pulled from the conditional statement, but nothing was output.

if season == s_fruit.keys():

print(s_fruit.values())

What syntax should I modify? Help me T..T

dictionary

>>> Season = 'Spring'
>>> s_fruit = { 'Spring' : 'Strawberry', 'Summer' : 'Watermelon'}
>>> s_fruit[season]
"Strawberries."
>>> s_fruit.get(season)
"Strawberries."
>>> Season = 'Autumn'
>>> s_fruit[season]
Traceback (most recent call last):
  File "<pyshell#12>", line 1, in <module>
    s_fruit[season]
KeyError: 'Autumn'
>>> if season not in s_fruit:
    print("no fruit for", season)


No fruit for autumn
