python总结

hell.py:

def parse_data():
    with open(r"G:/人民币货币对.txt",mode="r") as f:
       itle_list = f.readline().strip().split("\t")
    with open(r"G:/人民币汇率中间价历史数据.txt", mode="r", encoding="utf-8") as f:
        all_list = []
        for line in f:
            line_list = line.strip().split("\t")
            all_list.append(line_list)
    return  itle_list,all_list

def parse_condition(condition,seq):
    column, value_s = condition.split(seq)
    ind = itle_list.index(column)
    for line_list in all_list:
        value_t = line_list[ind]
        yield value_t,value_s,condition

def entry_point():
    condition = input(">>> ")
    if (">" in condition):
        for value_t,value_s,condition in parse_condition(condition,">"):
            if value_t > value_s: print(value_t)

    if ("<" in condition ):
        for value_t, value_s, condition in parse_condition(condition, "<"):
            if value_t < value_s: print(value_t)

    if ("=" in condition ):
        for value_t, value_s, condition in parse_condition(condition, "="):
            if value_t == value_s: print(value_t)


itle_list, all_list = parse_data()
entry_point()
input('输入任意字符结束')

用pip install pyinstaller，然后pyinstaller -F  hello.py，可以看到dist目录有个hello.exe和__internal目录（上面的文件采用绝对路径，改成相对路径，将文件放在__internal目录），拷贝这两个可点击使用
