The following code reads a file line by line, printing the uppercase version of each line, without ever explicitly reading from the file at all: Demo for line in open('main.py'): # Use file iterators to read by lines print(line.upper(), end='') # Calls __next__, catches StopIt...

To convert a string to uppercase in Python use the upper() method. The upper() method is a built-in Python function that converts all lowercase characters
2 Create a function that will return another string similar to the input string, 3 but with its case inverted. 4 For example, input of "Mr. Ed" will result in "mR. eD" as the output string. 5 ''' 6 import string 7 uppercase = string.ascii_uppercase ...
defto_uppercase(string): returnstring.upper() 5.创建 PySpark UDF 创建自定义 Python 函数后,使用 “pyspark.sql.functions” 模块中的 UDF 函数构造 PySpark UDF。 “udf()” 函数应接收自定义 Python 函数作为参数。自定义函数注册为 UDF,以便它可以应用于 DataFrame 列。
return s.upper() # 示例 print(to_uppercase("Hello, World!")) # 输出: "HELLO, WORLD!" 1. 2. 3. 4. 5. 例题15:生成斐波那契数列的前n项 def fibonacci(n): if n <= 0: return [] elif n == 1: return [0] elif n == 2: ...

print('*%abc%'.strip('*%')) 15.upper()方法 ''' upper()方法: Return a copy of the string converted to uppercase. 将字符串中的所有字符转换成大写字母,并返回一个字符串副本 同lower()方法对应 ''' print('abcdaAKJFA'.upper())
