检查字典是否包含命令输出中的某个字符串

Question

I'm new to learning python and pexpect and I'm trying to check if a dictionary contains a certain string from some command output but I'm having trouble.

So say I send some command called "list" to my terminal, it outputs details of a certain product:

->list
Color: Maroon Red
Height: 150cm
Code: 4KG-LV
Material: Aluminum
Brand: Toyota 
#and hundreds of more lines...

I have a variable that represents a dictionary that outputs this when I print it using 'print(license_type)':

{'license': '4kg-lv'}

I basically want to check if the code '4KG-LV' from the output of the list command is equal to the value '4kg-lv' from the license in the dictionary.

Doing this:

exp.sendline("list")
exp.expect('(?<=Code:\s).*(?=[\r\n])')
firstString = exp.after
print(firstString) 

parses the output of the list command using regex and gets/prints the value 4KG-LV. I can confirm this works.

If I were to put all of this in a python script and check if the two values are equal (ignoring capitalization), it should pass the check. However, when I try to check if the first string (the code from the list command) is in the dictionary, it outputs 'NOT EQUAL'

exp.sendline("list")
exp.expect('(?<=Code:\s).*(?=[\r\n])')
firstString = exp.after

# convert dictionary to string
secondString = str(license_type)

if firstString.lower() in secondString.lower()
    print("EQUAL")
else:
    print("NOT EQUAL")

I'm not allowed to change the key names/capitalization of what's in the dictionary. I tried converting the dictionary to a string and also used .lower() to convert both strings to lowercase. I'm not sure what I did wrong and would appreciate any help or references.

Answer 1

Instead of converting the dictionary to a string just access the value of the key license and convert it to a lowercase string and check if the firstString and it are equal. I am assuming that the regex you are using is correct.

license_type = {'license': '4kg-lv'}
exp.sendline("list")
exp.expect('(?<=Code:\s).*(?=[\r\n])')
firstString = exp.after

if firstString.lower() == license_type.get("license").lower():
    print("EQUAL")
else:
    print("NOT EQUAL")

I tested it out in my iPython shell so it should work:

In [3]: "4KG-LV".lower() == license_type.get("license").lower()
Out[3]: True
