some_string = "wtf" some_dict = {} for i, some_dict[i] in enumerate(some_string): i = 10Output:>>> some_dict # An indexed dict appears. {0: 'w', 1: 't', 2: 'f'}💡 Explanation:A for statement is defined in the Python grammar as: for_stmt: 'for' exprlist 'in' ...
Many built-in Python functions expect only ordinary strings and it is impossible to fake it in any way. There is no way to get the full functionality of regular strings from LazyString, except to convert LazyString to str, like this: str(f('some string')) Some methods of the str class...
python中int() python中int(-3.5),数据类型一、数字(int)Python可以处理任意大小的正负整数,但是实际中跟我们计算机的内存有关,在32位机器上,整数的位数为32位,取值范围为-2**31～2**31-1,在64位系统上,整数的位数为64位,取值范围为-2**63～2**63-1。对于int类型
numbers (like in Pascal), or giving the user the ability to define both the iteration step and halting condition (as C), Python’s for statement iterates over the items of any sequence (a list or a string), in the order that they appear in the sequence. For example (no pun intended...

Fortunately, the Python interpreter is easily called recursively, and there is a standard interface to call a Python function. (I won’t dwell on how to call the Python parser with a particular string as input — if you’re interested, have a look at the implementation of the-ccommand lin...
