Consider the use of the following methods: upper(), lower(), replace(), and find(). Upper() converts a string to its uppercase variant. Lower() converts a string to its lowercase variant. Replace(old,new) replaces the old occurrence of the substring old with the substring new. Find...
The last example string has no upper case letters, and thus the test fails. Note that in the above code, an empty string is considered a valid example of CamelCase. If we do: print(checkcamelcase(""))we will get: TrueIf we wish to disallow such cases, we can replace the “*” ...

Detect repeating substrings within a DNA sequence similar to the example provided in section 4.1 Replace long repeated patterns (length > 3) with a reference notation (start_index, length). When searching for a pattern lowercase and uppercase letters should be treated the same. ...
else块中的第 62 行说明了symbol字符串中的任何小写字符和非字母字符。 第63 行的缩进表示第 56 行的else语句与ifsymbol.upper() in charsA:语句成对出现,所以如果symbol不在LETTERS中,第 63 行执行。 else: # Symbol is not in LETTERS; just add it: translated += symbol...
From the output, you can see that the lowercase letter c appears 3 times, the space character appears 13 times, and the uppercase letter A appears 1 time. This program will work no matter what string is inside the message variable, even if the string is millions of characters long!

You should use uppercase letters and underscores to separate constants when naming them. You can generate long or short constant names depending on the function of the constant utilized in the context. Module Module.py,long_module_name.py You can use a Python module to import data into your ...
