With the simple function I am able to get data stored in response variable. With a print statement I can get the data showing correctly.
ec2_client = boto3.client("ec2")
def instance_list(instance_name):
response = ec2_client.describe_instances(
Filters=[
{
'Name': 'tag:Name',
'Values': [ instance_name ]
}
]
)['Reservations']
return response
#print(response)
if __name__ == '__main__':
my_instance_list = instance_list("example-*")
However while trying to import the value of response from the above function to another function, getting error as NameError: name 'response' is not defined
def my_list():
list = instance_list(response)
print(list)
Looks like something unidentified.
您需要将变量传递给下一个函数,例如
my_list(instance_list())
the basic idea is to use return value of one function to another function
Your function should be this:
def my_list():
# List is equal to the response value of instance list.
list = instance_list("example-*")
print(list)
def add_five_to_number(number):
number += 5
return number
def print_number(number):
higher_number = add_five_to_number(number)
print(higher_number)
test_number = 3
print_number(test_number)
# Returns 8
