我是 python 和這個(gè)論壇的新手。在線學(xué)習(xí)對(duì)我來說不起作用，所以我不能只去找導(dǎo)師。這可能是我忘記的一些小事。我歡迎您能給我任何幫助。我試圖使輸出看起來像這樣： Her name is Emmylou; 她有望于 2021 年秋季畢業(yè)；她的賬單已付清；她的專業(yè)是考古學(xué)；她屬于這些學(xué)校俱樂部——攝影、表演和歡樂合唱團(tuán)Emm = {'name' : 'Emmylou', 'graduate' : 'Fall 2021', 'bill' : 'paid', 'major' : 'Archeology', 'clubs-' : 'Photography, Acting and Glee'}for Key, Value in Emm.items():print(f"Her {Key} is {Value} and she is on track to {Key} in {Value}; Her {Key} is {Value}; Her {Key} is {Value}; She belongs to these school {Key} {Value}")輸出很混亂，當(dāng)我運(yùn)行它時(shí)看起來像這樣：Her name is Emmylou and she is on track to name in Emmylou; Her name is Emmylou; Her name is Emmylou; She belongs to these school name EmmylouHer graduate is Fall 2021 and she is on track to graduate in Fall 2021; Her graduate is Fall 2021; Her graduate is Fall 2021; She belongs to these school graduate Fall 2021Her bill is paid and she is on track to bill in paid; Her bill is paid; Her bill is paid; She belongs to these school bill paidHer major is Archeology and she is on track to major in Archeology; Her major is Archeology; Her major is Archeology; She belongs to these school major ArcheologyHer clubs- is Photography, Acting and Glee and she is on track to clubs- in Photography, Acting and Glee; Her clubs- is Photography, Acting and Glee; Her clubs- is Photography, Acting and Glee; She belongs to these school clubs- Photography, Acting and Glee

正如其他人告訴你的那樣，你正在迭代字典，并且在每次迭代中，鍵和值都會(huì)被替換并打印在新行中。
如果你想使用字典在一行中打印，你可以嘗試將字典轉(zhuǎn)換為數(shù)組并使用 format 方法打印。
Emm = {
'name' : 'Emmylou',
'graduate' : 'Fall 2021',
'bill' : 'paid',
'major' : 'Archeology',
'clubs-' : 'Photography, Acting and Glee'
}
items = []
for (key, value) in Emm.items():
items = items + [key, value]
print("Her {} is {} and she is on track to {} in {}; Her {} is {}; Her {} is {}; She belongs to these school {} {}".format(*items))

首先，我假設(shè)您實(shí)際上已經(jīng)在代碼中縮進(jìn)了 print 語句，否則它根本無法工作。
問題是，對(duì)于每個(gè)循環(huán)，您都在所有位置填寫相同的鍵/值對(duì)。
根據(jù)目的，您可以通過執(zhí)行以下操作來獲得聲明：
Emm = {'name' : 'Emmylou', 'graduate' : 'Fall 2021', 'bill' : 'paid', 'major' : 'Archeology', 'clubs-' : 'Photography, Acting and Glee'}
print(f"Her name is {Emm['name']} and she is on track to graduate in {Emm['graduate']}; Her major is {Emm['major']}; Her clubs - is {Emm['clubs-']}")
迭代字典時(shí)可能面臨的另一個(gè)問題是，除非使用 python 3.7 或更高版本，否則無法保證項(xiàng)目在字典中保存的順序。因此，您的鍵/值對(duì)可能不會(huì)按照它們進(jìn)入的順序出現(xiàn)。

在您的代碼中，您將迭代數(shù)據(jù)中的每個(gè)鍵值對(duì)；因此，您最終打印了 5 次，每次都使用一個(gè)鍵值對(duì)，而不是打印 1 次，每次都使用所有鍵值對(duì)。
嘗試這個(gè)。
Emm = [
('name', 'Emmylou'),
('graduate', 'Fall 2021'),
('bill', 'paid'),
('major', 'Archeology'),
('clubs-', 'Photography, Acting and Glee'),
]
flat_items = [item for pair in Emm for item in pair]
print("Her {} is {} and she is on track to {} in {}; Her {} is {}; Her {} is {}; She belongs to these school {} {}".format(*flat_items))
