I have a Python script that is generating string with many characters and I need each string to create a folder with its name. But do not stick to the problem, because what I really want to know is how to limit that string to a desired size and store it in a variable. For example:
stringGrande = "gerando string com muitos caracteres e preciso de cada"
stringPequena = stringGrande (limitada)
print stringPequena
Resultado: gerando string com muitos
for example
The string type is iterated in Python and allows you to access its content via slices . For example, texto[1:5] would return from the first to the fourth character of texto .
>>> print('anderson'[1:5])
nder
If you omit the first value, Python will understand that it is zero, starting at the beginning of the text:
>>> print('anderson'[:5])
ander
However, if the value entered after the colon exceeds the text size, it will only be returned to the end of the text:
>>> print('anderson'[1:30])
nderson
In this way, to limit a text to a number N of characters, just do texto[:N] .
Further Reading:
stringGrande = "gerando string com muitos caracteres e preciso de cada"
def diminuir(str):
max = 10 # Numero Maximo de caracteres Permitidos.
if len(str) > max:
return str[:max]
else:
return str
stringPequena = diminuir(stringGrande)
print stringPequena
