How can I write a python program to find all the consecutive numbers of pi with a million digits in a txt file by Python?
eg, if I want to find all the six-digit consecutive numbers, I can run the program and output might show
['123456', '234567'.....] are exist
if I want to find all the three-digit consecutive numbers, the output might show
['123', '234'.....] are exist
def fun(n, piList): l =  for i in range(len(piList)): subset = piList[i:i+n] sortedSubset = sorted(subset) firstOfSubset = sortedSubset targetSubset = list(range(firstOfSubset,firstOfSubset+n)) if subset == targetSubset: l.append(subset) if len(piList) - (i + n) ==0: break return l
A First Course in String Theory, l7 V22 81 which is valid for large z, to confirm our low temperature result in (22.89). Plot T(E), and calculate the (negative!) specific heat C in the high energy regime. (a) Find the ratio of the number of states available to the string and the Pls see attached file with very simple example of my problem. Imagine that I have this list of thousands of customers, who are listed in column B in the format "customer no+space+customer name". Now I want to extract ONLY the customer no from the text string in column B and insert it as number value in column A on the same row.
def fun(n): l =  for i in range(len(nums)): subset = nums[i:i+n] if subset == sorted(subset): l.append(subset) return l
Mathematical Biology: An Introduction with Maple and Matlab, Collagen, for example, is a fibrous protein found in skin and other organs. one quarter length from the next one and thus linked into very long strings. Each muscle cell contains large numbers of fibrous proteins that are capable of sliding Enzymes are globular proteins, but we have already discussed them, and we will Excel String Functions – Summary. Excel string functions can be used to retrieve specific characters within a string. You just saw how to apply Excel string functions across multiple scenarios. You can use any of the concepts above, or a mixture of the techniques described, in order to get your desired characters within a string.
You may try this:
>>> a = '12345564564' >>> def get_nums( nums, length ) : ... for i in range(len(nums)) : ... selection = nums[i:i+length] ... if len(selection) < length : break ... yield selection >>> for n in get_nums( a, 6 ) : print n ... 123455 234556 345564 455645 556456 564564
Random string generator - Special, Based on your input, get a random alpha numeric string. The random string This is an important tool if you want to generate a unique set of strings. The utility Delimit objects within random strings with: and delimit each random string with: line break. Output wrap is on off. Output Box - Random strings/passwords will display here.
Thanks for the ideas. I have solved this problem.
My method is using two for loops first to creat a consecutive number list, eg. ['0123456', '1234567', '2343456',......, '9012345']
Then I check 'if' any of the above list items is excisting 'in' the long pi and append the existing list item to a empty list and finally print it.

Information Systems Security: Second International Conference, , Then for each web site, select a long string from a web page that is frequently web sites attach session specific strings in image names and other HTML text. This data amounted to about 1.1TB in HBF form and would have been about Let’s say, you want to get a substring of the first 12 characters from a string. We can use the Substring method and pass it starting index 0 and length of the substring 12 to get the first 12 char substring from a string. The following code snippet is an example of retrieving a 12 chars substring from a string. // A long string
Extract Numbers From String Using Java Regular Expressions, If you want to extract only certain numbers from a string you can and we want to extract 6B1BC0 which is 6 characters long, we can use: As the manual says: "strlen() returns the number of bytes rather than the number of characters in a string.", so if you want to get the number of characters in a string of UTF8 so use mb_strlen() instead of strlen().
- Please add a more detailed example to explain exactly what you mean. It might also help to add some code to show what you've tried so far, even if it's just a rough attempt / idea.
- I have opened a txt file containing million digit in python and it is now a string containing million of digit. I want to find all the seven-digit consecutive numbers within this string.
- @goxywood So, does this text have one single string of millions of digits or there are any separators between them, like a white space? Can you display a snapshot of this text file?
- @a_r I have elinminated all the space. It is now ' '3.141592653589793238462643383279502884197169399375105820......' milion of digit in python. It is now one single string
- you should not try to build the whole list right away, it's too big and likely overflow the memory and take a lot of time to get built. try returning elements one-by-one, when they are really needed.
