在使用python搜索文件中的字符串后，如何打印此内容？

Question

我可以搜索这些值，但在执行此文件log.txt时，我遇到了一个难题，即如何以这种格式打印

Dlog = 0
MeanDlog = 102
i_min = 22 


Dlog = 10
MeanDlog = 10
i_min = 20

我有一个file.txt，它多次重复这些行，但是它的值改变了，我需要像这样保存这些行

在执行该文件后，以这样的方式打印

Dlog = {0, 10} 
MeanDlog = {102,10}
i_min = {22,20}

这将对您有用：

variables = dict() #Create a dictionary to store the split lines

with open("input.txt") as i_file: #Open the file
    for line in i_file:
        if line == "\n" or line.find("=") == -1: #Skip blank lines and lines with no equals sign
            continue
        name, value = line.strip("\n").split(" = ") #Split lines into two parts based on the "=" sign

        if name not in variables:
            variables[name] = list()

        variables[name].append(int(value))

with open("output.txt", "w") as o_file: #Can be changed to whatever file you want to write to
    for item in variables:
        temp = str(variables[item])
        temp = temp.replace("[","{").replace("]","}").replace(" ", "")
        o_file.write(item + " = " + temp +"\n")
