read) Help on method_descriptor: read(...) read([size]) -> read at most size bytes, returned as a string. If the size argument is negative or omitted, read until EOF is reached. Notice that when in non-blocking mode, less data than what was requested may be returned, even if no...
函数readBytesUntil() 从数据流中读取确定字节的数据到指定缓存地址,读取确定长度数据、或读取到终止字符、或超时时终止 和readBytes() 相比多了终止字符串 语法(Syntax): stream.readBytesUntil(character, buffer, length) stream:从 Stream 类 继承的实例 character:终止字符(char 类型) buffer:存放数据的指定缓存...
defrepeat(word, n):print(word * n) 如果我们像这样调用它,它会显示蒙提·派森歌曲《芬兰》的第一行。 repeat('Finland, ',3) Finland, Finland, Finland, 这个函数使用print函数来显示一个字符串,但它没有使用return语句返回值。如果我们将结果赋值给一个变量,它仍然会显示这个字符串。 result = repeat('F...
# Read a file character by character using a for loop This is a four-step process: Open the file in reading mode. Use a for loop to iterate over the file. Use a nested for loop to iterate over each line. The nested for loop will read the file character by character. ...
Python-tesseract is an optical character recognition (OCR) tool for python. That is, it will recognize and "read" the text embedded in images. Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine. It is also useful as a stand-alone invocation script to tesseract, as it can re...
