str转dict常用方法是json.loads(str),但遇到双引号会报错转换失败。本文介绍另一种方法:ast.literal_eval(str) importast str="{"name":"name1","pwd":"pwd1"}"dict=ast.literal_eval(str) dict['name']='name2' 如果是str是单引号时,可以用json.loads() importjson str='{"name":"name1","pwd"...
用eval从字符串转换为字典时报错: File "test.py", line 43, in d1 data = eval(a) File "<string>", line 1, in <module> NameError: name 'true' is not defined 解决: globals = { 'true': 0 } # --- data = eval(a, globals) 若继续报错: File "test.py", line 43, in d1 dat...
一般转换str为dict都用的json.loads,但是如果str开头为""就会报错,但是却可以用ast.literal_eval image.png image.png 在看看''开头的str转换为dict image.png
一个字典通过format()函数转换后就会由dict变为str, 例如: 1 2 3 4 5 a="156464654654" b="652683126541" c="{'username':'%s','password':'%s','Submit': 'dre'}"%(a,b) # c = eval("{'username':'%s','password':'%s','Submit': 'dre'}"%(a,b)) print(type(c))#(输出<class '...
解决: globals = { 'true': 0 } # --- data = eval(a, globals) 若继续报错: File "test.py", line 43, in d1 data = eval(a) File "<string>", line 1, in <module> NameError: name 'false' is not defined 解决: globals = {...
