使用 Python 搜索项目列表并返回列表的所有元素

Question

I have a large list of lists that looks like this...

[[16W1509462 , FR-CHJAV-VSDB4234HL , 30.5, 42.0, 0.75, JAVA ],

[16W1509463 , FR-CHJAV-BT-VSDB4234HL , 30.5, 42.0, 0.75, JAVA ],

[16W1509463 , FR-CHJAV-BT-VSDB4234HL , 30.5, 42.0, 0.75, JAVA ],

[16W1509473 , FR-CHJAV-BT-VSDB4234HR , 30.5, 42.0, 0.75, JAVA ],

[16W1509473 , FR-CHJAV-BT-VSDB4234HR , 30.5, 42.0, 0.75, JAVA ],

[16W1509481 , FR-CHJAV-VSDB4834HD , 30.5, 48.0, 0.75, JAVA ],

[16W1509481 , FR-CHJAV-VSDB4834HD , 30.5, 48.0, 0.75, JAVA ],

[16W1509503 , FR-CHJAV-BT-VSDB6034HD , 30.5, 60.0, 0.75, JAVA ],

[16W1509503 , FR-CHJAV-BT-VSDB6034HD , 30.5, 60.0, 0.75, JAVA ]]

I'm developing a program for my company so when an operator scans an item(the first element in the list is the item number), it will show them the description, length, width, thickness, and paint color.

I would like to store the item number they scan in a variable then search for that item in the list of lists then show them the specs of the item such as length, width, thickness so on.

I've checked many other forums and to no avail I have not found anything that seems to do what I need so I'm not sure if this is even possible

Essentially I would like the output to look like this

---

Item scanned: 16W1509462

16W1509462 , FR-CHJAV-VSDB4234HL , 30.5, 42.0, 0.75, JAVA

Answer 1

I assuming that each value stored in the nested list is a string except for the numbers. Also, I am assuming that there are no duplicate item numbers like in your sample list. Then this should work, if I understood your question properly.

item_to_scan = '16W1509462'
for sample in sample_list:
    if sample[0] == item_to_scan:
        print(sample) # or you can do whatever you want to do with the sample

Input:

sample_list = [
    ['16W1509462', 'FR-CHJAV-VSDB4234HL', 30.5, 42.0, 0.75, 'JAVA'],
    ['16W1509463', 'FR-CHJAV-BT-VSDB4234HL', 30.5, 42.0, 0.75, 'JAVA'],
    ['16W1509473', 'FR-CHJAV-BT-VSDB4234HR', 30.5, 42.0, 0.75, 'JAVA'],
]

Output:

['16W1509462', 'FR-CHJAV-VSDB4234HL', 30.5, 42.0, 0.75, 'JAVA']
