我想制作一个程序，使用termcolor制作文本彩虹，但我不知道如何将字符串转换为字母
代码：
from termcolor import colored
def rainbow(a):
alphabet = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'
,'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z']
a.split(str(alphabet))
print(colored(a, 'red'), colored(a, 'yellow'), colored(a, 'green'), colored(a, 'blue'), colored(a, 'magenta'),
colored(a, 'red'), colored(a, 'yellow'), colored(a, 'green'), colored(a, 'blue'))
rainbow("text")
实际上，字符串就像一个字母列表。你可以这样做：
string="text"
for letter in string:
print(letter)
如果你想在一个字符串中给字母上色，试试这个：
# Make sure the library is OK, I don't know it, just copy your code.
from termcolor import colored
# fill the dict for all letters yourself
lettercolors = {'a':'red','b':'blue','t':'yellow','e':'blue','x':'green'}
string="text"
for letter in string:
print(colored(letter,lettercolors(letter)),end='')
print('');
def split(word):
return [char for char in word]
print(split('text'))
#['t', 'e', 'x', 't']
我想你需要这样一个简单的函数。你的问题不是很清楚。
使用list()包装器：
print(list("text"))
输出：
['t', 'e', 'x', 't']
import itertools
import sys
def colored(ch, color):
# fake function as I dont have termcolor
sys.stdout.write(f"{ch}.{color} ")
def rainbow(a):
colors = ['red', 'yellow','green','blue','magenta']
#double it 1 2 3 => 1 2 3 2 1
colors2 = colors + list(reversed(colors))[1:]
#zip brings items of 2 lists together. cycle will just cycle through your
#colors until a is done. `a` itself is split merely by iterating over it
#with a for loop
for ch, color in zip(a, itertools.cycle(colors2)):
# print(f"{ch=} {color=}")
colored(ch, color)
rainbow("text is long enough to cycle")
部分输出：
t.red e.yellow x.green t.blue .magenta i.blue s.green .yellow l.red o.red n.yellow g.green .blue e.magenta n.blue o.green u.yellow g.red h.red .yellow t.green o.blue .magenta c.blue y.green c.yellow l.red e.red
第页。S
看起来colors2 = colors + list(reversed(colors))[1:-1]可能会避免在循环重新启动颜色时将红色输出加倍。这可能需要一些仔细的测试。
我偷了自行车。
