1. # Join
    2. print("and".join(["Jack", "Tom"]))
    3. > Jack and Tom
    5. print("and".join(["Jack", "Tom", "Jessica"]))
    6. > Jack and Tom and Jessica
    8. # Format
    9. print("你和{}".Format("我"))
    10. > 你和我
    12. print("{}你和".Format("我"))
    13. >我你和

    当然还有 %s ，但更推荐使用format，任何在设计到字符替换的都可使用到

    1. with open("{}_name.txt".format(api), "a+") as f:
    2.     f.write("{}, {}\n".format(uid["user-id"], uid.string))
    3.     f.close()
    5. string_to_sign = '{}\n{}'.format(timestamp, app_secret)
    7. msg = "You get a new version. {}\nThe download link : {}\n".format(get_version, get_url)
