如何返回完整形式的实验室测试（最初存储为首字母缩略词）以及每个测试的相应要求

Question

例如：

提示用户：“请输入所需测试的首字母缩略词。”
用户输入（测试的首字母缩写）

Print("The test you have requested for is: " + Full form of an acronym. 

必须提示用户输入20次

我有excel格式的测试列表，但无法加载和读取它们。下面是我的代码：

Lab_Tests = {
    "ALAP": "ANTI LIVER ANTIBODY PROFILE",
    "RAF": "RHEUMATIOD FACTOR",
    "CCP": "ANTI-CCP ANTIBODY",
    "ENAP":"ANTI-ENA PROFILE",
    "DNA":"ANTI DOUBLE STRANDED DNA ANTIBODY",
    "C3": "C3 COMPLEMENT",
    "C4": "C4 COMPLEMENT",
    "CALU": "CALCULI, URINE",
    "OTA": "OSTASE",
    "CAE": "CAERULOPLASMIN",
    "AAT": "ALPHA-1 ANTITRYPSIN",   
}

Packing_Lits = input("Please indicate your tests in this packing list:")

def FullName(acronym):
    if acronym not in Lab_Tests:
        print("Please print a valid acronym")
        return
    return Lab_Tests[acronym]
