如何精简Python中打印CSV数据的大量print语句？

针对你分散的print语句，有几种高效的精简方式，同时还能提升代码可读性：

1. 使用f-string（Python 3.6+ 优先推荐） #

这是最简洁直观的写法，直接在字符串中嵌入变量和表达式，同时把重复计算的结果存为变量避免冗余：

avg = round(get_avg(people))
diff = people[owner]["plugs"] - avg

print(f"\n{people[owner]['first_name']} {people[owner]['last_name']} owns the most buttplugs with a total of {people[owner]['plugs']} buttplugs!")
print(f"That's {diff} more buttplugs than the average of {avg}!\n")

2. 使用str.format()方法 #

兼容Python 3.6之前的版本，通过占位符填充内容：

avg = round(get_avg(people))
diff = people[owner]["plugs"] - avg

print("\n{} {} owns the most buttplugs with a total of {} buttplugs!".format(
    people[owner]['first_name'],
    people[owner]['last_name'],
    people[owner]['plugs']
))
print("That's {} more buttplugs than the average of {}!\n".format(diff, avg))

3. 字符串拼接（不推荐，可读性差） #

将所有内容拼接成完整字符串后一次性打印，注意数值类型需要转成字符串：

avg = round(get_avg(people))
diff = people[owner]["plugs"] - avg

print("\n" + people[owner]['first_name'] + " " + people[owner]['last_name'] + " owns the most buttplugs with a total of " + str(people[owner]['plugs']) + " buttplugs!")
print("That's " + str(diff) + " more buttplugs than the average of " + str(avg) + "!\n")

4. 利用print多参数特性 #

print支持传入多个参数，默认用空格分隔，适合简单场景：

avg = round(get_avg(people))
diff = people[owner]["plugs"] - avg

print("\n", people[owner]['first_name'], people[owner]['last_name'], "owns the most buttplugs with a total of", people[owner]['plugs'], "buttplugs!")
print("That's", diff, "more buttplugs than the average of", avg, "!\n")

核心优化点：把重复计算的round(get_avg(people))存为变量avg，既减少重复计算开销，也让代码更简洁。
