How to convert str to int in python

In python, you can use the built-in int() function to convert a string to an integer.

The following is an example:

string = "123"
number = int(string)
print(number)# 输出:123
print(type(number))# 输出:<class &#x27;int&#x27;>

int()The function can also accept a second parameter, indicating the base of the string. For example, convert a binary string to an integer:

string = "1010"
number = int(string, 2)
print(number)# 输出:10

In addition to using built-in functions, you can also use other methods for conversion, such as using the eval() function or using the string method isdi<strong class="keylink">git</strong>() Judgment If the string contains only numeric characters, then use loops and math operators to build the integer. However, using the int() function is the most common and recommended method.

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
