我正在尝试安装manim,(请参阅此处:https : //github.com/3b1b/manim)。我正在使用 python 版本 3.7.7。我已经按照这个视频https://www.youtube.com/watch?v=ZltiKHFWmv8的步骤操作,直到我尝试安装 requirements.txt ( https://github.com/3b1b/manim/blob/master/要求.txt)。我在终端上收到此错误:
错误:找不到满足要求 requirements.txt 的版本(来自版本:无)
错误:没有找到 requirements.txt 的匹配分布
有谁知道如何修理它?
我正在尝试解决一个问题,可以在第13.2.4节中的Pieter Spronck编写的The Coder's Apprentice中找到.这是我到目前为止编写的代码:
english_dutch = {"last":"laatst", "week":"week", "the":"de", "royal":"koninklijk",
"festival":"feast", "hall":"hal", "saw":"zaag", "first":"eerst", "performance":"optreden",
"of":"van", "a":"een", "new":"nieuw", "symphony":"symphonie", "by":"bij",
"one":"een", "world":"wereld", "leading":"leidend", "modern":"modern",
"composer":"componist", "composers:componisten" "two":"twee", "shed":"schuur", "sheds":"schuren"}
text = "Last week The Royal Festival Hall saw the first \
performance of a new symphony by one of the world's leading \
modern composers, Arthur 'Two-Sheds' Jackson."
def clean(t):
t = t.lower()
t = t.split()
new_t = ""
for word in t:
new_word = ""
for letter …
Run Code Online (Sandbox Code Playgroud) 我在 scanf 和 sscanf 参数中遇到过类似这样的表达式:
sscanf(buffer, "%d,%100[^,]%*c%f", destination_pointer)

或者
scanf("\n%99s", destination);

解释这些的正确方法是什么?我知道“%s %c %d”之类的东西是什么,而且 %100 或通常的“%number”是要读取的输入的大小。但是剩下的呢?我能找到的只是基本的例子,没有接近这个复杂的东西。有参考指南吗?
