从Python中的Dictionary打印特定键的值

Question

我有Input.txt，此文件的内容是：

Name1=Value1
Name2=Value2
Name3=Value3

所需的输出：获取key==Name1的值。

条件：这需要由Python中的Dictionary实现。

Answer 1

with open("Input.txt", "r") as param_file:
    text = param_file.readlines()
    d = dict(x.strip().split("=") for x in text)
    for k, v in d.items():
        if k == "Name1":
            print(f"{d[k]}")

Answer 2

您可以做

with open("Input.txt", "r") as param_file:
    text = param_file.readlines()
    dc = {y.split("=")[0]:y.split("=")[1] for y in [i for i in a.split(" ")]}
    print(dc["Name1"]) if "Name1" in dc else None

将输出

Value1
