How to repeat a word letter by letter python-CodePudding

I need to repeat a word letter by letter using Python, comparing it to the size of another text.

For example:

ex_text = "I am an example test text" #25 characters''
ex_word = "coding"
rep_word = ""
    
for i in ex_word:
    while len(rep_word) < len(ex_text):
        rep_word  = i
    
print(rep_word)

I'm trying to print something like: codingcodingcodingcodingc

PS: actually it would be better if the output also consider the white spaces, like: c od in gcoding codi ngco

Divide the length of ex_text by the length of ex_word to get the number of repetitions. If they don't divide evenly, use a slice to get the extra characters from the next repetition.

multiples, remainder = divmod(len(ex_test), len(ex_word))
rep_word = ex_word * multiples   ex_word[:remainder]

CodePudding user response：

Create a generator that produces the letters you want to repeat:

def coding():
    while True:
        for l in "coding":
            yield(l)

print("".join(list(c for (_, c) in zip("I am an example test text", coding()))))

displays: 'codingcodingcodingcodingc'

CodePudding user response：

You can iterate range(len(ex_text)) and use modulo len(ex_word) to get index of char in ex_word

ex_text = "I am an example test text" #25 characters''
ex_word = "coding"
rep_word = ""

for i in range(len(ex_text)):
    index = i % len(ex_word)   # modulo
    rep_word  = ex_word[index]

print(rep_word)

Result

codingcodingcodingcodingc

Here is the solution:

ex_text = "I am an example test text" #25 characters
ex_word = "coding"
rep_word = ""

while len(rep_word) < len(ex_text):
    for i in ex_word:
        rep_word  = i
        if len(rep_word) >= len(ex_text):
            break

print(rep_word)

CodePudding user response：

ex_text = "I am an example test text"

ex_word = 'coding'
rep_word = ""

while len(ex_text)>len(rep_word):
    rep_word =ex_word
while len(ex_text)!=len(rep_word):
    rep_word = rep_word[:-1]

print(rep_word)

CodePudding user response：

Here is an alternative using itertools.cycle:

from itertools import cycle


ex_text = 'I am an example test text'
ex_word = cycle('coding')
rep_word = ''

while len(rep_word) < len(ex_text):
    rep_word  = next(ex_word)

print(rep_word)

The code above will result in the following output:

codingcodingcodingcodingc
