在 python 中为多个字符串粘贴 0 类函数

Question

我想实现的很简单，在R中我可以做到

paste0("https\",1:10,"whatever",11:20),

如何在 Python 中执行此操作？我发现了一些东西，但只允许 :

paste0("https\",1:10).

任何人都知道如何解决这个问题，这一定很容易做到，但我找不到方法。

Answer 1

根据您提供的 link， 这应该可行：

["https://" + str(i) + "whatever" + str(i) for i in xrange(1,11)]

给出以下输出：

['https://1whatever1', 'https://2whatever2', 'https://3whatever3', 
'https://4whatever4', 'https://5whatever5', 'https://6whatever6', 
'https://7whatever7', 'https://8whatever8',
'https://9whatever9', 'https://10whatever10']

编辑：

这应该适用于 paste0("https\",1:10,"whatever",11:20)

paste_list = []

for i in xrange(1,11):

    # replace {0} with the value of i
    first_half = "https://{0}".format(i)

    for x in xrange(1,21):

        # replace {0} with the value of x
        second_half = "whatever{0}".format(x)

        # Concatenate the two halves of the string and append them to paste_list[]
        paste_list.append(first_half+second_half)

print paste_list

Answer 2

@Jason，我建议您使用以下两种方法中的任何一种来完成此任务。

✓ 通过使用 list comprehension 和 zip() 函数创建文本列表。

Note: To print \ on screen, use escape sequence \. See List of escape sequences and their use.

Please comment if you think this answer doesn't satisfy your problem. I will change the answer based on your inputs and expected outputs.

texts = ["https\\" + str(num1) + "whatever" + str(num2) for num1, num2 in zip(range(1,10),range(11, 20))]

for text in texts:
    print(text)

"""
https\1whatever11
https\2whatever12
https\3whatever13
https\4whatever14
https\5whatever15
https\6whatever16
https\7whatever17
https\8whatever18
https\9whatever19
"""

✓ 通过定义一个实现上述逻辑的简单函数 paste0() 到 return 文本列表。

import json

def paste0(string1, range1, strring2, range2):
    texts = [string1 + str(num1) + string2 + str(num2) for num1, num2 in zip(range1, range2)]

    return texts


texts = paste0("https\\", range(1, 10), "whatever", range(11, 20))

# Pretty printing the obtained list of texts using Jon module
print(json.dumps(texts, indent=4))

"""
[
    "https\\1whatever11",
    "https\\2whatever12",
    "https\\3whatever13",
    "https\\4whatever14",
    "https\\5whatever15",
    "https\\6whatever16",
    "https\\7whatever17",
    "https\\8whatever18",
    "https\\9whatever19"
]
"""
