PreparedStatement

如何在一个代码中替换两个项目，即：

ResultSet

Answer 1

您只需使用if检查您的专线是否包含'2099'或'2010'，如下所示：

from random import randint

with open("data.json", "rt") as fin:
    with open("dataout.json", "wt") as fout:
        for line in fin:
            if '2010' in line:
                fout.write(line.replace('2010', str(randint(1990, 2007))))
            if '2099' in line:
                fout.write(line.replace('2099', str(randint(1800, 1900))))

Answer 2

使用两种replace()方法：

from random import randint
with open("data.json", "rt") as fin:
    with open("dataout.json", "wt") as fout:
        for line in fin:
            fout.write(line.replace('2010', str(randint(1990, 2007))).replace('2099', str(randint(1800, 1900))))

Python line.replace多个字符串
