Python 如何在一行中写入打印字符串变量和循环范围变量
我试图循环一系列变量,并将它们写入新行上的输出文件 我研究并尝试了f.write、print()、printf和f' 代码返回频繁的语法错误,或者我传递了太多参数,或者无法连接字符串和整数 定义变量Python 如何在一行中写入打印字符串变量和循环范围变量,python,Python,我试图循环一系列变量,并将它们写入新行上的输出文件 我研究并尝试了f.write、print()、printf和f' 代码返回频繁的语法错误,或者我传递了太多参数,或者无法连接字符串和整数 定义变量 House=范围(0,40,10) 循环通过每个变体: casenumber = 0 #used in the filename for ham in House: # CREATE INDIVIDUAL YML (TEXT) FILES
House=范围(0,40,10)
循环通过每个变体:
casenumber = 0 #used in the filename
for ham in House:
# CREATE INDIVIDUAL YML (TEXT) FILES
casenumber = casenumber + 1
filename = 'Case%.3d.yml' % casenumber
f = open(filename, 'w')
# The content of the file:
f.write('My House has this many cans of spam', House)
f.close()
这应该适合您,我想您应该将编号
ham
写入文件
casenumber = 0 #used in the filename
#Iterate through the range
for ham in range(0,40,10):
# CREATE INDIVIDUAL YML (TEXT) FILES
casenumber = casenumber + 1
filename = 'Case%.3d.yml' % casenumber
f = open(filename, 'w')
# The content of the file:
#I assume you want to write the value of ham in the file
f.write('My House has this many cans of spam {}'.format(ham))
f.close()
我们将在这里得到4个文件,其内容在前面
Case001.yml #My House has this many cans of spam 0
Case002.yml #My House has this many cans of spam 10
Case003.yml #My House has this many cans of spam 20
Case004.yml #My House has this many cans of spam 30
此外,您还可以使用with
语句打开您的文件,这将为您关闭文件,如下所示
casenumber = 0 #used in the filename
#Iterate through the range
for ham in range(0,40,10):
# CREATE INDIVIDUAL YML (TEXT) FILES
casenumber = casenumber + 1
filename = 'Case%.3d.yml' % casenumber
with open(filename, 'w') as f:
# The content of the file:
#I assume you want to write the value of ham in the file
f.write('My House has this many cans of spam {}'.format(ham))
f.write中的House
(“我家有这么多垃圾罐头”,House)
可能也是ham
文件。write只需要一个参数,所以你应该将它拆分为对f.write
的多个调用。不需要拆分对f.write()的调用,只需要使用str.format()
或f-string
。我认为OP期望f.write()
的行为与print('something value is',something)
相同。
