fibonacci sequence python

Define the function first, then call the function in the while loop and get the result you want.def getfib (num): fib=[1,1] for I in range (num+1): tmp=fib[-1]+fib[-2] Fib.append (TMP) return FIB[NU M-1]while true:num=input (' Please input a num:\n '). Strip () try:num=int (num) print (GETFIB (num)) exc Ept:print (' invalid ') continueAfter execution, enter a number, and the script automatically draws the Fibonacci number of the corresponding bit.

Python Reverse Sequence Method Instance analysis, python Reverse Sequence instance analysis This article describes how to reverse a sequence in Python. We will share this with you for your reference. The details are as follows: A

The sequence we're talking about in Python includes :1. String (a sequence consisting of multiple characters)2. List3. Tuples# What are the similarities and differences between lists and tuples? list=[1,2,3]print type (list) tuple= (all in a)print type (tuple) # lists and tuples are containers that can contain any type of element (even a

Python sequence II and Python sequence II String All standard sequence operations also apply to strings, but the strings are immutable. String formatting: # Example> 'num is: % d' % 18 'num is: 18 '>>> 'str is % s' % 'string' 'str is string # The width and accuracy of the

Python sequence and Python SequencePython contains six built-in sequences: List, tuples, strings, Unicode, buffer objects, and xrange objects. Common sequence operations include indexing, sharding, adding, multiplication, and membership. There are also built-in functions such as length (len), minimum value (min), and m

There are two sequences, a, B, the size is n, the value of the sequence element arbitrarily shaped number, unordered;Requirement: To minimize the difference between the and of [sequence A and] and [sequence B elements] by exchanging the elements in A/b.1. Combine the two sequences into a sequence and sort them to get s

There are many things we need to pay attention to when using Python DNA sequences. In fact, there are many problems in constant learning. Next we will look at in detail how to conduct related technical schools. Ms is my brother's rotation project: Given A bunch of Python DNA sequences, that is, A string consisting of characters A, C, G, T, count the occurrence frequency of all subsequences whose lengths are

S2[2]>>>print S3[1][2]Because the elements of the list can be changed, you can assign a value to an element of list:GT;GT;GT;S2[1] = 3.0>>>print S2If you do this to a tuple, you get an error message.So, you can see that the reference to the sequence is by S[3: Other citation methodsRange reference: Basic style [lower limit: Upper limit: Step length]>>>print S1[:5] # from start to subscript 4 (the elements of subscript 5 are not included)>>>print s1[2

problem: You have a data series that you want to use to extract the required values from or shorten the sequenceAnswerEG1: List derivationThe simplest way to filter sequence elements is to use list derivation. Like what:>>> mylist = [1, 4,-5, 10,-7, 2, 3,-1]>>> [n for N in mylist if n > 0][1, 4, 10, 2, 3]>>> [n for N in MyList if n [-5,-7,-1]EG2: Generator expression iterationsa potential flaw in using list derivation is that it produces a very large

Min (iter,key=none) or min (arg0,arg1,..., key=none) (2.5 start support keyword parameter) return to ITER or (Arg0,arg1,...) Minimum value, if key is specified, the key must be a callback function that can be passed to the sort () method for comparison Reversed (seq) (2.4) takes a sequence as a parameter and returns an iterator that is accessed in reverse order Sorted (Iter,func=none,key=none,reverse=false) takes an iterative object as a
