Tutorial Python: eacarsaichean le fuasgladh

Tha Python na chànan prògramaidh sìmplidh, ach fìor adhartach.

Tha sinn air grunn artaigilean a sgrìobhadh mu Python, agus tha an t-àm ann beagan cleachdaidh a dhèanamh.

San artaigil seo chì sinn cuid de eacarsaichean Python, a ’mìneachadh am fuasgladh ceum air cheum.

Ùine leughaidh tuairmseach: 4 minuti

Chì sinn còmhla teacsa cuid de eacarsaichean agus am fuasgladh.

Eacarsaich air ais

Sgrìobh gnìomh ris an tèid thu seachad sreang mar pharamadair, agus a bheir a-mach, air an sgrion, tionndadh neo-dhruim (air ais) den aon sreang. Mar eisimpleir bidh “abcd” gu bhith na “dcba”.

Gliocas: gus an eacarsaich seo fhuasgladh ann an dòigh chruaidh dh'fhaodadh tu slicing a chleachdadh.

# Solution for this exercise

def reverser(string):
    ind = (len(string) -1)
    new_string = ""
    while ind >= 0:
        new_string += string[ind]
        ind -= 1
    print(new_string)

def reverser_pro(string):
    reverse = string[::-1]
    print(reverse)

Eacarsaich rann

Sgrìobh gnìomh rhyme, a thèid seachad air liosta fhaclan mar pharamadair agus a gheibh facal a chuir an neach-cleachdaidh a-steach tron ​​​​ghnìomh cuir a-steach.

An gnìomh rhyme feumaidh tu coimeas a dhèanamh eadar am facal a chuir an neach-cleachdaidh a-steach agus an fheadhainn a bha an làthair air an liosta roimhe, a’ coimhead airson rannan, air an tuigsinn mar fhaclan aig a bheil na 3 litrichean mu dheireadh co-ionann ris an fhacal a chuir an cleachdaiche a-steach.

Feumaidh na rannan an uairsin a bhith air an cur a-mach a’ cleachdadh an dòigh ceangail.

# Two solutions for this exercise, rhyme and rhyme_pro

def rhyme(listx):
    rime = []
    word = input("Enter the word you want to find rhymes for: ")
    for element in listx:
        if element[-3:] == word[-3:]:
          rime.append(element)

    if not rime:
        print("No rhymes corresponding to the past word were found!")
    else:
        output = ", ".join(el for el in rime)
        print(f"The rhymes corresponding to the word {word} are as follows: {output}")

def rhyme_pro(listx):
    rime = []
    parola = input("Enter the word you want to find rhymes for: ")
    rime = [el for el in listx if el[-3:] == word[-3:]]
    if not rime:
        print("No rhymes corresponding to the past word were found!")
    else:
        output = ", ".join(el for el in rime)
        print(f"The rhymes corresponding to the word {word} are as follows: {output}")

Eacarsaich factaraidh

Sgrìobh aon gnìomh ath-chuairteach a tha a 'cunntadh an factaraidh de àireamh ainmichte.

Fuasgladh

def factorial(n):
    if n == 1:
        return n
    else:
        result = n * factorial(n-1)
        return result

Eacarsaich Fibonacci

Nella Sreath Fibonacci saor an asgaidh, is e gach àireamh suim an dà àireamh air thoiseach oirre, mar eisimpleir:

1, 1, 2, 3, 5, 8, 13 (…)

Sgrìobh gnìomh ath-chuairteach a bheir a-mach àireamhan an t-sreath Fibonacci, taobh a-staigh stairsneach sònraichte a shuidhich an neach-cleachdaidh.

Fuasgladh

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

limit = int(input("Enter the number of values ​​in the series you want to see: "))

for num in range(1, limit+1):
    print(fibonacci(num))

Eacarsaich Dèan tomhas air an àireamh

Dèan an geama “Guess the Number” a’ cleachdadh Python. Bidh an geama a’ gineadh àireamh air thuaiream agus feumaidh an neach-cleachdaidh a thomhas, a’ faighinn sanasan ma tha an àireamh airson tomhas nas àirde no nas ìsle na an tomhas.

Riatanasan

1. Gineadh àireamh air thuaiream: Cleachd an leabharlann random gus àireamh air thuaiream a chruthachadh eadar 1 agus 100.
2. Eadar-aghaidh cleachdaiche: Cruthaich eadar-aghaidh cleachdaiche loidhne-àithne sìmplidh a leigeas leis an neach-cleachdaidh oidhirpean a chuir a-steach.
3. Molaidhean: Leig fios don neach-cleachdaidh ma tha an àireamh tuairmseach nas àirde no nas ìsle na an tomhas.
4. Cunnt oidhirp: Cum sùil air an àireamh oidhirpean a rinn an neach-cleachdaidh.
5. Deireadh a' Gheam: Cuir crìoch air a’ gheama nuair a bhios an neach-cleachdaidh a’ tomhas an àireamh no a’ co-dhùnadh stad.
