需要帮忙。 如何从 .t​​xt 中提取列表并使用输入进行排序

Question

Okay So, i have a dilemma. I have a document filled with names of countries. Now i need to get the list in python with open. Done that. However I am required to make a program that inputs a letter and gives all the countries that start with that letter. cant seem to figure it out. Any help would be appreciated

Answer 1

def getcountries(country_list, letter):
    output = []
    for x in country_list:
        if x[:1].lower() == letter.lower():
            output.append(x)
            print (x)
    return(output)

pass this function the list of country names, and the letter to search for. it will print the name of each country, and will return a list of those countries.
