Python_时间戳匹配最近

时间戳匹配最近的情况

时间戳匹配

函数式编程-代码示例

 for timestamp in timestamps:
     closestTimestamp = min(index,key=lambda datetime : abs(timestamp - datetime))

def nearest(items, pivot):
    return min(items, key=lambda x: abs(x - pivot))

def nearest(items, pivot):
    return min([i for i in items if i <= pivot], key=lambda x: abs(x - pivot))

传统编程代码示例

# -*- coding: utf-8 -*-

def find_match_time(base_file, candidate_list,match_gap=1):
    match_time = None
    for sigle_file in candidate_list:
        pose_timestamp = float(sigle_file)
        timestamp_gap = abs(pose_timestamp - float(base_file))
        if timestamp_gap <= match_gap:
            match_time = sigle_file
            match_gap = timestamp_gap
    if not match_time:
        raise Exception('time not match', base_file)
    return match_time
	
	
if __name__ == "__main__":
	extra_list=[,"1659173362","1659173359","1659173360","1659173361","1659173362"]
	choose_file="1659173360"
	time_dat = find_match_time(choose_file, extra_list)
	print(time_dat)
