There aremanyways to save a Python dictionary to file, and then load it into memory later. The five techniques I use most often are: pickle, json, numpy, string serialization, and custom function. Each technique has pros and cons. Suppose you have a Python dictionary like so: src_dict =...
def save(dict): if isinstance(dict, str): dict = eval(dict) with open('a.txt', 'w', encoding='utf-8') as f: # f.write(str(dict)) # 直接这样存储的时候,读取时会报错JSONDecodeError,因为json读取需要双引号{"aa":"BB"},python使用的是单引号{'aa':'bb'} str_ = json.dumps(dict,...
# Function to save website name and password to CSV file defsave_credentials(website_name, password): encrypted_password = encrypt_password(password) withopen('credentials.csv','a', newline='')ascsvfile: writer = csv.writer(csvfile) writer.w...

The only solution I found so far is to manually copy the intrinsics one by one into a dictionary, save this dictionary, and them manually reconstruct the intrinsics object, as the intrinsics object does not allow being pickled (it has no dictionary, presumably because it's a Cython constru...

This means the expression 'a'*20 is replaced by 'aaaaaaaaaaaaaaaaaaaa' during compilation to save a few clock cycles during runtime. Constant folding only occurs for strings having a length of less than 21. (Why? Imagine the size of .pyc file generated as a result of the expression '...
