我有一个字符串，希望一次性替换字符串中的所有值

Question

str1 = "series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few **sentences** should be organized into paragraphs."

REPLACE_STRING = {"series":"web" , "sentence":"long paragraph"}

输出：

web of long paragraph that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few **long paragraph** should be organized into paragraphs.

基本上需要一次性用字典中的键替换str中的所有值

Answer 1

一次性：

str1 = str1.replace('series', 'web').replace('sentence', 'long paragraph')

使用循环：

for to_replace, replace_with in REPLACE_STRING.items():
    str1 = str1.replace(to_replace, replace_with)
