这是我第一次使用Python,我在让它输出我想要的格式时遇到了麻烦。我希望输出能够并排显示。可能是因为我累了,我就是搞不明白该怎么做。

我的代码:

def cToF():
    c = 0
    while c <= 100:
        print(c * 9 / 5 + 32)
        c += 1
def fToC():
    f = 32
    while f <= 212:
        print((f - 32) / 1.8)
        f += 1






print (cToF(),fToC())

输出结果:

all of the numbers from cToF()
all of the numbers from fToC()

我希望的输出结果:

all of the numbers from cToF()    all of the numbers from fToC()

如果你想要打印出类似这样的内容;

cToF first Element fToC first element
cToF second Element fToC second element
...

你可以把两个列表合并在一起进行打印。

下面是一个你可以使用的示例代码;

import pprint
def cToF():
    c = 0
    ret_list = []
    while c <= 100:
        ret_list.append(c * 9 / 5 + 32)
        c += 1
    return ret_list

def fToC():
    f = 32
    ret_list = []
    while f <= 212:
        ret_list.append((f - 32) / 1.8)
        f += 1
    return ret_list

def join_list(first_list, second_list):
    length_of_first_list = len(first_list)
    for i, val in enumerate(second_list):
        second_list[i] = (" - "if (length_of_first_list-1) < i else first_list[i], val)
    return second_list

pp = pprint.PrettyPrinter(indent=4)
pp.pprint(join_list(cToF(), fToC()))

目前,cToF函数会运行并打印出所有的值,然后fToC函数也会运行并打印出所有的值。你需要改变生成这些值的方式,这样才能把它们并排打印出来。

# generate f values
def cToF(low=0, high=100):
    for c in range(low, high + 1):
        yield c * 9 / 5 + 32

# generate c values
def fToC(low=32, high=212):
    for f in range(low, high + 1):
        yield (f - 32) * 5 / 9

# iterate over pairs of f and c values
# will stop once cToF is exhausted since it generates fewer values than fToC
for f, c in zip(cToF(), fToC()):
    print('{}\t\t{}'.format(f, c))
# or keep iterating until the longer fToC generator is exhausted
from itertools import zip_longest

for f, c in zip_longest(cToF(), fToC()):
    print('{}\t\t{}'.format(f, c))  # will print None, c once cToF is exhausted

如果你在使用Python 2,请把xrange替换成range,把izip_longest替换成zip_longest
