There are many formulas in the history of Pi Pai, in which Gregory and Leibniz found the following formula:Pai = 1-1/3+1/5-1/7 (...)This formula is simple and graceful, but in the ointment, it converges too slowly.If we rounded up
/(5*7) +...+n/((2*n-1) * (2*n+1)), require the end of the first N-1 term and the absolute value of the first n and the difference to be less than 0.00001. and output the n at this time.

(func)即可。Two: Partial function (one of functools the functions in the module)1在介绍函数参数的时候,通过设定参数的默认值,可以降低函数调用的难度。而偏函数也可以做到这一点。2 int() Functions can convert a string to an integer, and when passed in only the string, the int() function defaults to decimal conversion:int(‘12345‘)12345But int() the function also provides additional base parameters, the default value is 10 . If you pass in base a parameter, you can do an n-binary conversion: >>> int ( ' 12
