wi-fiが途切れた時にrequests.get が停止する場合の対処について

Question

前提・実現したいこと

requests.getがwi-fiが一時的に詰まったことで処理が止まってしまった時に途中から再開する(requests.getをやり直す)方法があれば教えて頂きたいです。
内容としては,赤経赤緯(ra,dec)に合う天体をカタログから繰り返し引っ張ってくるもので、
カタログ検索の際にrequests.getを用いています。
これの実行中に一時的に回線状況が悪くなり処理が止まってしまい、検索がストップしたまま動かなくなっている状況だと考えています。

が後に延々と続いていくのですが、ここで止まっており、途中でwi-fiが一瞬繋がらなくなったので、外部との接続が必要なps1corn関数(詳細にはrequsts.get)で詰まったと考えています。

試したこと

プログラムを中断/再開するため、ターミナル上で
Control + z (中断)
fg (再開)
を行いましたが、相変わらず進みません。
Control + c でプログラムを停止すればやり直せますが、いかんせん数時間かかるプログラムで、今どのループで停止しているか把握できていないため、なるべく途中から再開できる方法を見つけたいと思っているところです。

Answer 1

r = requests.get(url, params=data)
if r == "did not matched":
    while not r == "did not matched":
        r = requests.get(url, params=data)

とても汚いですがこれでどうでしょうか?
